I use Office365 Business (Premium). I love having ActiveSync push emails to my phone (vs. Poll), and if I grow my family I can manage contacts and services.
If you can clarify some things, I'm happy to give it a shot.
1) What language is your project
2) After it builds, do you want to store a copy of the build anywhere?
3) Do you want to use any particular system for deploying the build to the servers?
