Deciding tools to be used for source/version control for continuos developement

Which tools would be good for need of source and version control. Technology used language : C# IDE : Visual studion developer express edition. Database : mysql Team of 3 developers working from home and requiring to push code and .exe on one machine. Each developer is working on different project and has different production setup path. Current way: [] Changes are made by the developer on their local machine. [] Exe is build and is transferred over ammy admin or teamviewer. Challenges: [] Keeping track of changes done to the source code. [] Automatically displaying of version number for each release. Required workflow: [] Developer makes changes and tests the c# code locally on his machine. -requirement : incrementing version control on each build. [] He then pushes the source code to version control(github or bitbucket) [] Remotely logs on the production machine using RDP. [] Pulls the code on the prod machine. [] Creates exe. [] Runs the code. What is needed: Need suggestion from experienced developers on usage of tools (preferably open source or paid upto $30/INR 2000 per month). Define steps for workflow of transferring code from developers machine to production machine enroute github/bitbucket(Preffered since its already in use)
