Move from Spreadsheets to Relational Database

We are growing our business and need to reduce the number of independent spreadsheets that are used to track orders, production, scheduling, QC info ...... We are looking for a programming two work with us pretty intensely to move the project along. We have a pretty good idea as to the structure of the database and the relationships. We need get it in place and then work on forms and reports. the interface should also allow for us to easily write reports and do analysis on the data without having to re-engage the programmer. So selection of the appropriate software/database is important.
