newbie looking to sync access with MySQL

I have a potential customer that just called and would like to create a web site that would display secure info for their clients. Currently his employees are using a flat Access database to add, edit and delete records and he would like to keep it that way. Normally I would create a web manager for them to add, edit and delete the MySQL database. Is there an easy, reliable way to sync up Access with MySQL. Maybe a nightly script that could upload the contents of Access to MySQL. Would it be easier to start with ASP and SQL Server? Thanks, Tom
