152466 Posting my items on eBay

Folks, I post my items for sale (or for auction) on a site similar to eBay. Unfortunately, such posting is ONE ITEM at a time, and now with a few hundred items, and a lot of times updates, extremeley tedious. I was hoping to get a bid for a COMPLETE software tool that would take my straight forward spreadsheet of products, or, offer a table in an HTML/XML style page. On the loaded page or the HTML page, there are typical columns of item attributes such as Description, Title, Price, Start Price, ..., including the payment method. The rows are each one item - If I have 328 items, there will be 328 (329 if you include the title row :-) On that same page, I have also entered my login and password. I click a button on the page and it loads all my items. If you are interested, or think you can do this, I can provide substantially more detail. Please understand that you may need to look into how eBay (e.g. and in my case this OTHER eCommerce site) does submit a page, etc. The trick is that I have to generally login to eBay, then there are the session cookies (I THINK) then you submit your one item at a time to these ASP/PHP/SomethingElse pages. There may be a need for an executable, running locally on the machine, for doing some of the work for maintaining the session, or connecting to the site, or doing SOMETHING which I don't know what it will be now, but it is to get the job done and having such a piece of code will be ok. Thank you.
