Remote & Mobile Network access

I need a solution for the above statement

I have approximately 50 employees that need to access our NT 4.0 network while away from the home office.
1) Via a remote computer from satellite offices
2) Via a mobile laptop or PDA device

Any solution must include a high level of security because we deal in health care.
This is what I think we will need to do.
A) Setup a VPN
B) Remote offices will need a broadband connection (DSL or Cable Modem)
C) Mobile users will need wireless data/internet access
D) Log on authentication
E) File encryption

Well that?s what I know. I need help with how to implement.
i- Hardware solutions
ii- Software solutions
iii- Wireless data/internet service providers in upstate/Syracuse New York
iv- Setup and configuration

Any help from someone who has this experience will be greatly appreciated.
This is a nonprofit agency and we are currently applying for technology funding.

Your VPN services, whether they're running on a firewall, NOS, proxy server, router, or standalone VPN system, reside outside of your corporate network. VPN clients are implemented differently, but at the most general level, they insert authentication and encryption software between your Host site and client devices. The goal is to limit not only which users and hosts have access to your corporate systems, but more important, to ensure that the data transmitted over the Internet is encrypted sothat only authorized system hosts and remote users see the data. A VPN needs complete end-to-end packet encryption. Also consider, on the server side, if your VPN services, such as a firewall or proxy server, run on your own hardware, you should be aware that the encryption process could add a significant CPU load.
As a final note on VPN implementation, there are several protocols in use by the various vendors and not all VPN technologies interact well together. I have been working on 3 separate VPN installations and configurations for several months and each one is slighly different in its approach. In comparing the 3 with your scenario, I may have some additional insite for you so feel free to email me if there are specific needs you have regarding VPN or encryption.
