Creating a computer buy/sell page

i would highly enjoy it if the website could set up a web page where folks from far and wide could buy/sell there rigs because i would like to start to sell the comps i make. I would love some feedback on this and if it is already made pls tell me where i could find it. Thnxs so much!

ehh well there is some problems with that, one being no body is going to wait on you do get the parts shipped to you, then build it and you ship it to them

you could solve this by haveing a surplus of parts on hand but that requires quite a bit of spare coin

also they start to lose the value if its not custom made to their needs

i would maybe like to buy one of those rigs with a price of 450-500 dollers including os gimme some specs please.
