I admire your hard work and if you are simply honest, you'll make a ton of money.  We have a "kid" around our marina (I think he's 19) that started on one boat but by the time he was done, I think he had about 6 customers, maybe more.  He's the son of a local businessman and everyone supported him.  In his case, he had the tools and knowledge.  However, if someone just had the will and the time, I'm sure you could get some elder gentleman to take you under their wing.  Simple wax jobs are simple but when it comes to different degrees of oxidation, you really need someone with experience.  I don't think I'd be willing to tackle the wet-sanding jobs just yet. 
Good Luck!
