/diy/ - Do It Yourself

I've been thinking of starting an online store.
I've been making custom enclosures for amps, stereo equipment, boxes, etc. even joysticks.
My output isn't really great, as I take on each job as a individual work of art. I have been making them, for friends, friends of friends and receiving payment by mail.
It's obviously not the best way to do things, so I've been thinking about opening a small store page. I would obviously need a paypal account. I'm unsure on how to work out payments. I think if you sell something they take 3%.
However, some people just make arrangements and send the money directly. It involves a lot of negotiations and talking. I don't even really need a shopping cart system. Also, I'm stuck with only dealing with customers in the US, which I don't like.. as I'm not above sending something overseas if someone wants.
Anyone have any experience with selling items online, outside of the typical ebay store?

I'm making small electronics and enclosures by hand, want a simple way to sell them online through a webpage.
Looking for advice with anyone with any experience with selling items online, outside of the typical ebay store.

I work at a computer repair store, and we recently started doing in house motherboard repairs.
Having to solder jacks on laptops has really gotten me interested in electronics.
We throw out a lot of motherboards, hardrives, cd drives, lcds and things...
Any ideas on what I can scavenge off of these to use for projects?
Also, whats some basic tools should everyone have?
All I have is some pliers, wire strippers and a soldering iron.
