Former Florida Gov. Jeb Bush is launching an aggressive new campaign fundraising program inspired by a tiered system first pioneered by George W. Bush.

But the new plans are literally aiming much higher.

In a nod to his home state of Florida, Bush's donor program is called Mission 2016 JEB -- a NASA-inspired title for a program that will have three distinct tiers for top bundlers to aspire to as the campaign progresses.

The first tier, called Apollo, will be for bundlers who can help Bush raise at least $75,000. The second tier, called Endeavour, is for donors who reach at least $150,000. Top-flight bundlers will reach the Voyager level as they help rake in at least $250,000.

Several people familiar with the plans confirmed the details to The Washington Post on the condition of anonymity because they were not authorized to publicly discuss the plans. An e-mail detailing the program was also circulated to participants on Monday.

Top Bush aides began outlining the program's goals during a donor retreat in Kennebunkport, Maine late last week.

The retreat came as Bush's campaign, his leadership PAC and an allied super PAC announced approximately $119 million in combined contributions to boost his efforts, an astounding and record-setting sum for a candidate of either party. Bush's campaign raised about $11.4 million; his leadership PAC another $5 million and the super PAC, Right to Rise USA, collected about $103 million.

As part of the new program, the campaign has launched an "8 by Eight Fundraising Challenge" that seeks to entice top bundlers to find at least eight more people who can donate the maximum $2,700 to Bush's primary campaign by Aug. 1 -- for a total of $21,600. People who reach the goal will be invited to a party in Cleveland -- the site of the first GOP presidential debate -- on Aug. 6 and another dinner in Coral Gables on July 29.

Other events are also scheduled in the coming months, according to the e-mail message sent Monday. There's a fundraiser Tuesday night in Los Angeles and a breakfast event Wednesday in Pasadena, Calif., followed by a luncheon in Santa Barbara. A cocktail party hosted by Columba Bush will be held on July 22 in Washington. Bush is scheduled to attend fundraisers in Middletown, N.J. and Short Hills, N.J. on July 23; and two on July 25 in Long Island. On July 31, he'll raise money in Fort Lauderdale -- the same day he speaks at the National Urban League conference there. Fundraisers will be held in the San Diego region on Aug. 3; in Nashville Aug. 4; and in Nantucket on Aug. 20.

Another retreat for large donors is being planned for some time in October in Houston.

Jeb Bush's donor program is seeking to replicate what George W. Bush did during his 2000 and 2004 campaigns. During both his presidential bids, the former president rewarded Pioneers, who helped raise at least $100,000; Rangers, who helped raise $200,000 or more; and Super Rangers, who helped collect at least $300,000. A fourth level, called Mavericks, was for donors under the age of 40 who helped bundle at least $50,000.

The tiered system helped George W. Bush become the most prolific fundraiser of either party until that time, though such sums have been far exceeded in more recent years by super PACs and other presidential campaigns.

On Monday, Jeb Bush's campaign is set to announce its own donor program for younger Republicans in the 21 to 35-year old range. Modeled on the Mavericks and the Young Professionals program launched by Right to Rise, it will be co-chaired by Bush's sons, Texas Land Commissioner George P. Bush and Jeb Bush Jr., people familiar with the planning said.

Younger donors -- in many cases junior partners at top law or accounting firms and other mid-level executives -- will be able to help raise as much as $50,000. But the campaign is working on ways to reward donors who help bundle less but are also willing to earn some "sweat equity," according to people familiar with the plans.

One potential scenario under discussion would involve rewarding a younger bundler who is able to raise $10,000 from close friends, family and colleagues, but also help aggressively promote Bush's campaign on social media or in other ways.

Details of the young donors' program, which didn't have an official name as of Monday morning, are also expected to be unveiled later Monday.
