Connecting multiple offices

I have four offices spread over the state with different ISP's.  I need to get them on the same network so they can all share files from a server in one location.  I have fairly extensive LAN knowledge but WAN knowledge is very minimal.  What do I need to get these connect with the least amount of cost/setup yet something reliable?  The offices are all connected a little bit differently.  Three have standard cable/dsl setups but one of them is piggybacking off of a T1 that is in the office complex I believe.  Thanks for your assistance.

Thank you very much.  Going to research VPN concentrators.  
You may also look into Cisco's DMVPN feature in IOS 12.4

It is the closest to a perfect solution as you can get.  In your situation where you're dealing with dynamic IP addresses on the branch offices, DMVPN will not require you to incur additional cost of getting Static IPs at your branches.
Also, if you already have existing Cisco routers at both your main site and branch offices, you can leverage that hardware (assuming they can support 12.4)
here is a link to this feature:

I hope this helps.
