Hi Jakub A., I noticed your profile and would like to offer you my project.
We have an existing website made on wordpress
WHAT WE NEED
1) Auctions plugin. Admin will publish an auction and users will bid in order to win the prize. A countdown (time left) counter for each auction. Real time updates. Very similar to ebay. Well coded.
2) Automatic bids. Users set a maximum amount to spend and the system will bid on theirbehalf everytime they get outbidded. They don't need to be in front of the computer or logged in. Very similar to ebay.
3) Auto clone ended auction. When a user wins an auction, the system will clone and re-post same auction.
WHAT WE HAVE
-We have user balance functions such as get_user_balance(), update_user_balance(), etc.
