Complete database development for a tutoring database

I had a previous freelancer who started this project and did not finish it. I need this project completed ASAP. It is for the completion of the development of a database application which acts as a management tool for a Home Tutoring business. The purpose of the database was to manage clients, tutors and track payments across the students \ clients and tutors. The current database has been developed in : .net 4.0, MSSQL express, Linq, c#. I have all of the current source code. This project is about 80% of the way through and there are only minor tweaks and fixes that need to be applied to get this completed. 1 of the more important items was that currently the database only functions from 1 computer. I need it to be able to be hosted on a machine and then simultaneously accessed by multiple computers to read \ write data. This is a relatively small project which had an initial budget of $440.00. Given that this is 80% completed i expect to only be paying somewhere near the remaining 20% of $440.00. I have all of the changes \ fixes and requests for this and the source code all ready to go for whoever takes the job. Again - i need this completed ASAP.
