Its a good idea to start off with this business. Good luck. I have been doing this in my locality, yes you will surely have legal problems if you try to publicize over a certain limit. Just get contacts thro office colleagues, relatives and friends. Do not post it on common ad-sites example craiglist and all. Be a lil bit careful and sense the people who call you. They may be sony\MS people who would be calling to check if you sell backups\do modding services. No business is risky. So just keep that in mind and do your best.
Also, with the present ps3 hack scene you cannot make any business because every consoles that are in the USA, will have firmware 3.60 or even more. You have to get your hands on with e 3 flasher. I would strongly recommend you to purchase the xbox modding kits like lizard, scorpion2 to flash the consoles.
