I am currently selling my all my Windows clients. They are currently hosted on a Windows 2003 server with HELM.
We currently have $344 due in monthly invoices. For a total of 15 clients. They all are resellers.
You can also take over the server if you want. It has the following specs:
P4 2.8 w/ HT
16 IP Addresses
1000gig Monthly Bandwidth
Owned MainEnable Pro License ($200)
DC: The Planet
The server price will be lowered soon to around $154 because I will be removing some no longer needed IPs and hardware.
