Remote Office Setup….Charge?

This is a basic question and hoping to get ‘ballpark’ figures from you guys. I know all the factors that come into place such as location, experience, etc. but give me an answer based on YOUR thoughts. What would you charge a client to setup a remote office which would include:

one domain controller
5 users
networking/connectivity to main office

These are just the basic requirements so you can get an idea of what I mean. Let me know. Thanks
