Upload products to Zen Cart store from Supplier CSV File

Our Supplier has provided a CSV/TXT file for us so we can bulk add products to our website, created with zen cart. We have tried thinking of ways of bulk uploading and was going to use easy populate, this is not a problem.

Our supplier provides the list with the following headings

Manufacture
Quickcode
Part Number
Price
Quantity in stock
Price
Title
and a link to the page

Our big problem is that we need the item descriptions for each item and images listing onto our website as well. We only have a link to each page so can only do this manually. I know that this can be done, but we are not sure how.

Therefore we need a program or a little coding to obtain the information from the suppliers website and uploading to our website, (so can be listed as a csv file and uploaded through easy populate)
We need to be able to change the prices and quantity in stock so this would need to be something that is easy for us to use on a regular basis.

Any questions please ask

P.S. We need this doing quite urgent so please ask any questions you need and provide your bid and the time frame of completion
