Create webpage where customers can enter orders which populates a database

We are a wholesale bakery business, currently servicing approximately 15 retail locations. The current ordering system is time-consuming - each week, the manager for each store completes an Excel spreadsheet (attached) detailing how many of which products they want delivered each day. The forms are emailed to us, and we then manually aggregate the data so we can see what needs to be produced each day. Payment is not made online - instead, invoices are sent individually to each store at the end of each 2 week period (a system that we would like to retain). We would like to change this so that: a) ordering is done by each store manager by visiting a url and entering the order information on a page that looks similar to the attached spreadshet b) the data is written into a database (we would use the database that is part of the hosting plan we currently have with GoDaddy) We would then be able to easily export that data via .csv into Excel where we can easily create reports of what needs to be baked by day, by store, by product etc. The document attached has the specific workflow.
