Recommendation on VPN

I have a client that has a small office of about 13 computers no server. They are all independent except for a couple that run a program with a database for equipment tracking. They have a T-1 for internet access.I would like to setup 2 users with a vpn to be able to run this program and have its database run over the vpn. The database is only 6mb in size. The laptop is using a Verizon broadband card which speed tests at about 1.5 download and uploads at about 170kbps. Any recommendations for hardware and software to allow this. Currently uses Logmein to access the desktop internally and run but would like to move it to laptop and free up the desktop for another user.
