Hi,
I created a short estimation of how much time whould it take to create this site for you.
Here is my estimation:
FRONTEND
User registration, with email confirmation 4 hours
User data management: edit, delete, view user data 4 hours
Auction management: post, edit, delete auction with image 5 hours
Bidding an auction 5 hours
ADMIN
Admin can view posted auctions and he can approve,reject or delete them. 5 hours
OTHER
Integrating and using the selected template 5 hours
creating database and table structure 3 hours
TOTAL HOURS 26 hours
Do you want a specific template or CMS for this site (Codeigniter, Drupal, .. ) ?
The price for this project would be: 250$
If you are interested please contact me.
Regards
