I'm moving into a new apartment building in the next week~ or so and want to basically just run a small shop outside of the spare space in my room fixing people's computers/arcade machines/laptops/360 RRoDs etc... but I know that (specifically for the 360s) I'd have to void warranties to even look at the problem and not to mention computers can be real finicky even if you manage to fix them. I want to know if there's some way to cover my ass through some sort of signed paper that would basically say "if this shit goes to hell I'm not financially liable for your problems, sign here _________", is that something that I would be able to do or what steps I should take to protect myself from people trying to get a new laptop or whatever out of me? I don't suspect I would really break anything as I've done component level work for a while now and know what I should feasibly be able to fix by myself and what I should leave to someone more experienced.
I'm expecting mostly software issues on computers but I have the ability to potentially fix a lot of various problems with TVs/360s/laptops that would require me changing out components (generally blown transistors and caps which aren't all that hard) but I'm a bit wary as to the legal implication if something I do FUBARs someone elses property even though they asked me to fix it.
Also, just suggestions from anyone who has done this sort of thing before, whether through craigslist or your own apartment complexes or just word of mouth, I don't want to do what I did a few months ago which basically ended with me having like 200 units in my house at one point which I obviously couldn't keep up with by myself, or if you've modded 360s or homebrewed a wii, what kind of timeframe would I be looking at to do something like that and would I need any external equipment? I'm sure I can google it but there's generally a few tricks which people have that aren't always obvious when you start but you eventually learn.
Also any tips on pricing models wouldn't be a bad idea, I do a lot of work for local pawnshops and consignment shops where I generally charge about 10% of their asking price of the item which usually comes out to about 20~40$ for about 30 minutes worth of work but obviously that's a bit more clear-cut of a business setting.
edit: Also, I've heard you can just buy the warranty stickers for 360s online to replace the ones that say 'void' when you remove them, anyone who might have extra info on this let me know! (I'm sure this isn't legal or is frowned upon or whatever, but I've only heard of them and never seen them)
