I work for an established development company. We also have a hosting branch and at the moment have over 100+ cllients running on both shared and dedicated severs. We run at the moment 16 servers. As our main focus is software development, hosting is not our big aim but we would like to bring it up. We get a great flow of new clients daily but now we are sending them away to other companies because our staff is only trained to handle our software and not actual server support.
My suggestion to instead of investing in getting new employees was to find us a partner in the hosting branch. The partnership we are looking for is a company to team up with and for them to take over all the client support and server managment.
If you have any questions please feel free to PM me.
