zen cart v1.5.3
easy populate 4 (with which you can add/update items in your store simply by uploading a csv file. which can be created/edited using OpenOffice, a free tool)
ups 2014 - shipping module
usps v15 - shipping module
I will give you a shopping store exactly like this one: http://stor9.com
including the categories and items. I will give you the 2 csv files with which by changing a column, you can delete all the items. the csv files give you an example how to upload your own items.
You have to provide:
1, your usps account# (register at usps.com to obtain the account#)
2, your paypal API username, password, and API key (login your paypal, go to profile>my business info>selling tools>API>update) you can call paypal support. If you are not willing to give me this information, and you cannot get paypal to work on your site, you will have to pay me extra gigs for helping you set it up later. (it costs me time to teach you how to do it.)
3, give me an email you want to use on your site, e.g. for customer service.
4, give me a logo (495x264px), and header-banner image (1000x125).
5, your hosting account access
