1. You are definitely overestimating how hard this is. Look up contract CFO firms, and you should be able to get part-time support for logistics like that (as well as helping you get your books set up and do taxes).

2. Many are non-profits or have a mission that is unrelated to them making a profit. They often are funded by VC firms, companies who would like to provide services to companies in the accelerator once they have money (law firms, etc), and companies that want to raise their own credibility in the startup scene (3dsystems, or area-focused companies like GE maybe funding accelerators that work in batteries). Some also get government grants.
