asp / mysql database issue

I have multiple websites that I want to all use/query the same database [login to view URL] is the main website the database has been converted into mysql. the other websites still use msaccess [login to view URL] [login to view URL] [login to view URL] currently when you add a product to the shopping cart it redirects to the [login to view URL] shopping cart so if I could keep everything as is but just use the same database. when i change a price or product in the bestbuyuniforms mysql database I want it to also change for the other websites too so basically all share one database Im not sure the best way to go about it. It might be as simple as redirecting from the msaccess database to the bestbuyuniforms mysql database but Im sure there will be some asp scripts that will need to be modified. If you think you have a good idea and can give me a good price let me know and we can talk more and let you take a look at the back end coding.
