Can you just go right for top shelf jobs if you are new to the biz? I would bet there's a lot of competition for this type of work.
You should be able to bid your services on a site like uship.com which could help you build a network of referrals.
Hot shotting is an extremely competitive business. I like the suggestion of doing Uships, etx to see if there is money to be made. Your rig will have huge miles in just a year, and in many cases will depreciate much more than the potential profit.
Love the idea of someone being self employed.... just suggest one look at all data, no easy money in hot shotting unless one gets a special contract, which is very rare.
