What is an RSP?
I don't know if dish has a similar setup, but through perfect-10 and metron you can get directv installs. I didn't do business with metron, but I already had a perfect 10 account so becoming an installer for them was easy. Problem is, they had too many, and they didn't give me enough work to pay for the insurance they required, so I just canceled it (the insurance). AFAIK, I still have a contract, they just won't give me any work unless I give them proof of insurance.
The real problem with being a contractor is that most places want to force workman's comp on you. The company I contract with forces it on us, but they deduct it from our check. They jacked me to the tune of $1700 last year. I got hurt once (stepped on a nail at a junky residence). That cost $200 in doctor's fees and prescriptions + 8 days off because I got cellulitus (or whatever). The WC paid for the doctor and medicine, but in MS, you have to miss like 2 weeks of work to qualify for WC.
I'm thinking about getting a workman's comp policy. It'll cost $750 and would cover all my employees. There are 2 caveats: It won't cover ME, and I don't have any employees. WC is a big scam.
I've successfully fought it with perfect 10 and another company because MS does not require the owner of a business to cover themselves with WC.
Watch out for the mom and pops. Make sure you get paid weekly. You don't want D* or E* nailing them with a buttload of chargebacks to the point of going out of business (while they owe you money), and that happens every day.
Better still, if you can find a retailer who is running their installs through metron or Perfect 10, you might be able to cut a deal with them to switch to you. A better deal than might be found locally. They can save some scratch (Perfect 10 charges retailers out the wazoo), and you can make a little extra.
