Ajax related products

I have a module/feature called related poducts in oscommerce. It displays related products on [login to view URL] and is controlled from [login to view URL] in admin. [login to view URL] is similar to [login to view URL] in the way it works. Its easy to use, but its a lot of admin work to add product options. I'm looking for a service provider to make the related products option available in the product edit admin page using ajax (the page were you update the product with prices, images etc. There are two options for the related products in admin. First you choose the product you want to work with, and then you shoose the products you want to add. For the project, I would like to make this one option instead of two. You would already be on the product page, so you wont need to choose that option, only choose the related products you want to add.
