Linux support on hosted server. Trouble shoot current server and install updates to applications

I need somebody to troubleshoot a Linux server which we have hosted, there are several updates that are required to be installed and some general maintenace and advice on an ongoing basis.

I am reviewing the applications we use and would like to be able to run my requirements past the winning bidder and discuss how to move forward, as ther are several utilites and application I would like to run and need to ensure that the enviroment is correct.

I will write and agree a full project plan with the winning bidder, the intial cost for looking at the server and resolving the intial problems can be done on a paid hourly or daily rate or fixed cost to suit.
