I use SunShop e-commerce system with some modifications.
It work perfectly now, but I need to have add-on to admin section also.
It must to allow me import information about products from Excel/CSV files.
SunShop have already similar function, but it's inconveniently a little.
Script should do automatic calculations of the prices also within importing, and updating prices of existing items.
All formulas and forms will be provided to selected programmer.
It's urgent work a little, I'm in pending your bids.
The winner can receive additional works for my site in the future also.
