need help with a SNES

[DigitalJeff51]

i recently took apart a SNES that my cousins gave to me cause it didnt work well i ordered the tools need to take it apart and managed to get it running again

and now i want to start refurbishing old consoles and bringing them back to life and i have been doing some research on this and found out that a majority of the time the system will just need a good cleaning to replacing the pin connector
now what i want to know is where could i by a replacement pin connector for the snes

and how much do you think i should charge i was think 25 bucks but that sounds a little to much
i also want to do nes, segas, and n64s
is there anything else i should know before try to do this any skills i should know beforehand

Aside from anything else you need to know, if you wanna go down the route of fixing consoles then seriously consider fixing newer consoles as well - if you can change pin connectors on a SNES, I'm fairly sure you can fix most simple problems on a 360. I can buy a working SNES for £25 or so, and it'll probably come with games and controls. Charging to fix old consoles just doesn't seem like a business plan that will have business coming to it.
