Product Importing for Magento

We are building a website in Magento using a full-width template that we added custom design to. [login to view URL] The client is interested in building software that will import products automatically for him. Here are the details; Take this product for example. This is one among thousands that will be entered into the database at some point. [login to view URL] [login to view URL] There is a name, a title, a quick description, a price, a longer description, a link to [login to view URL], Additional Information section, Publisher, Year, Designer, Language, Edition, Time, Minimum Age, # of players, Themes, Mechanics, an image and an embedded or linked video. that is a LOT of information and a lot of data entry. I think we discussed this a week or two ago... but to recap, I want a quote on what it would cost to have your programmer to code/build a program that will sift through a site and datamine. In other words, the software would go through a site and build a database systematically and capture the above or similar information. Then once that database is complete, then code a method of automatically uploading that database into magento database. That would save me a million man hours in typing.
