I have web servers running Linux and using WebMin to administer to these servers. I have setup and am providing virtual hosting to clients. I have some small general configuration issues and require tasks like upgrading the Kenneral on a older machine. I would like to know that the person has good Linux knowledge and how to configure WebMin to work with Linux. For the most part I am able to do this but have some outstanding issues that could be fixed. Some of the servers are up and serving pages so I can not afford down time of more than a couple hours in the evening. I would also like to use this person for any future support and upgrades.
Bid Smart - The lowest bidder doesn't always get chosen, far from it. Persuade your buyer why they should pick you - and they will.
Research - If John has paid more than $500 a contract for his last 10 project, why would you think he is interested in your $10 bid? Check up on the buyer, bid what he expects, and deliver quality to match.
Read - Please read the bid request - I cannot emphasise this enough - if you do not read the bid request then you will not be chosen, this is pretty much certain. Mention the bid request specifically in your application, and don't forget to repeat the key deliverables.
Innovate - Suggest features the bidder didn't mention, talk about future extensions to the project, and discuss whether you think his or her approach is a good idea. Show interest, intellect, and willing.
