Stealth Vendor! Good way to get PERMANENTLY BANNED from RC, too!
Anthony...it's a 'nice' idea...but SORRY, IMO, you've got no shot to make any $ doing this...there are plenty of people out there, already trying...if they last a year, they've done 'good'...
The wholesalers will NOT give preference to someone spending a few hundred dollars, every few weeks...the 'good stuff/high end' pieces go to the best customers...the 'real' dealers import their own pieces, and cut out the WS.
You need to learn A LOT more about the hobby, first.
If you insist on trying, start very small, keep the 'investment' to a minimum. I'm sure you will find someone selling off their 'prop system', cheap! (because they're giving up!)
The experience/education is what your dad will be paying for.
