Hi,
I am ready to do this project. I can do it in either: MySQL, Oracle, Access, PostGreSQL or MSSQL. You may choose (I think MySQL as per your description). Implementation is second database is 50% if you want to. I'll make all the Primary keys and Indexs as well, so you have an optimal database (if the ER-diagram can be optimized I'll let you know as well).
I can do this within one day, no problem.
Kind regards
Jerry
