Linux contractor

I am looking for a linux expert that can help us on an hourly basis as required. We have a 1gb cloud instance with ubuntu 10.04 lucid. The usual items are installed. Currently there is only one project and website on the server. The main software running is mySQL and Ruby. I need an experience webmaster and Linux expert to help set up and maintain the server instance. For the right person this will be the easiest money you'll ever make. To get the right person, I am happy to pay a minimum charge fee. Work will be adhoc, as required. Our requests will not be super urgent, project is in development, nothing needs to be done ASAP, so we dont need someone on call. So you can be in any time zone. Initially we need some simple DNS issues sorted out, we need to finish off server set up, and tighten up security. We dont need help programming or with development but you can get involved if you have those skills, depending on cost. Additional skills/experience looked upon favourable: mysql, ruby on rails, [login to view URL] grid system, HAML, CSS and SASS, and compass. What I am looking for now is a goto person to help and solve Linux issues. This is not a fulltime or part time position. Would suit someone already employed or has regular work and wants to make some extra money capitialising on their skills and experience.
