Since it's only Thursday the best help I can give you is this.
DO NOT BUY A SPRINTER TOMORROW!!!
You are looking at a career. Treat it like a career. That means a LARGE amount of study and education. Think about how many months and hundreds of hours education is required for a successful career as a plumber, paralegal, realtor or any other field. You need a similar foundation for this career. You can get a crash course, which you can't do in other fields, by reading back at least 3 years in the General, Newbies and Recruiter forums.
You don't have to read every single word written in 3 years but you must read every single thread title and then you must read every word of every thread that sounds remotely educational. That is a lot of reading. If you apply yourself, and you can devote full time every day to doing so, you can probably do that reading in the next week or so. Then you can take a few days to digest it and decide if this is right for you. Then, if all that works out to a go, you can go for a van on the 30th when they have to make the sales to make the monthly quota and may give a better deal.
Your other more economical option is to take the advice of driving for an owner. You still need to do the reading and studying. There is far FAR more to this than holding a steering wheel. Even if you were going to work for your cousin's plumbing shop you'd still need to learn plumbing. Otherwise you might as well just get the hose and spray your face.
