Web Developer
I need a custom ebay like site for bitcoins or using stock credit on it. I need it to let you pay the user verbally, like an agreement you agree on that's it. I need the site fixed so it can be upgraded in the future.
I need it to be fixed so you can upload something to the site and sell it.
All I ask is keep the buying and selling part verbal agreements only. Like sending the user stock credit virtually.
Bid on things on the website
Sell things on the website
Buy things on the website
All I ask is keep the programming simple and the website in a simple form.
I need a website for the web browser and one for the phone web browsers.
If you can put in a custom user admin for it also, then that will be great.
Thank you,
