We have a lot of this sort of work. Hourly is probably best so we can give you more tasks under this Freelancer assignment.
You must be FAST. And good communication is a MUST. Meeting deadlines, essential. I would like to see at least 5 completed assignments on Freelancer with high feedback score. Be sure to post at least 3 things you've done that are similar such as projects with other shopping carts or 1shoppingcart. Thanks
