Develop a small program/application for inventory tracking

I would like to know if it's possible to develop some application that does as follow: I have a retail website with products, those products have SKU, I enter the products manually, now I need to check constantly from my provider's website about the availability of those SKU, if the SKU is no longer available in my provider's website I need to take it out from my site. I need to automate the task of checking each SKU against my provider's public website. Also I keep all the SKU's on an Excel Sheet, so It could be smthg. that check that excel sheet against my provider website. That could work also. Please let me know if its possible, and how much would it cost to develop such thing and how long would it take.
