so you are looking for someone who is an expert in their field, will be on call 24 hours per day, and does not mind remotely connecting to your computer to fix any problem at any time, and works for less than $20 per hour. (assuming you only have 5 one hour computer problems in a year)
I have to say good luck, because I know most peoples companies that get them out of bed at 2 am to fix a problem do so for about $50 per hour at a 3 hour minimum charge.
Everyone here is more than willing to help, but we are also realistic. please be conscious of what you are telling people they are worth. If you want an expert, be prepared to pay for one.
