database on windows computer and android phone with synchronising - open to bidding

Hi, I#m looking for somebody who can program a database with several functions for me (see attachement). My computer is currently running with windows XP but it would be nice if the database for the computer could be installed on other windows versions too. I would like to be able to connect an unlimited amount of mobile phones to that database (at least 20). It would be nice if you could take the time to read the attached description and tell me if you would be able to program taht for me and what kind of budget would be necessary. Thank you. Best regards, Martin
