part-time windows/linux server tech

I need an experienced server tech (fluent in linux and windows server management that would assist me whenever I need) I currently need assistance with these server spec. 1) sever 2000 hosted with asp script, iis5 becomes unstable and need advice on fixing this. 2) mail server found huge bandwidth and need advice to lower down bandwidth and probably rebuild it. I need you to find out problems, and fix it. After you fix it, report to me and write down what you did. You will be paid on a 10-hour per unit basis. and you can estimate the working time before it. If this works out for both of us, I will be expecting to work with you on a longer term basis. So please bid on a 10-hour per unit basis. Thank you.
