need custom module to link images on server to existing nodes

I am looking for someone to write a custom script or module to link images on my web server to existing ubercart product nodes. Basically I have a program I use to publish new products from my point of sale system to my online ubercart store. I then have to upload each associated image one at a time to each product. This is very time consuming considering it takes about 13 clicks per product to upload a picture. I would like to change this process so that I simply FTP images to a designate landing directory and a script or process running in the background will grab the image, find the related node if it exists (if not then skip) and associate it with the node so the image will show up on the product pages. The script will be able to locate the proper product node by using a predetermined part of the file name as the sku number (probably the last x digits or something like that). Any takers? What would this cost?
