I need a graphic designer for designing a logo

I'm planning to re-design a logo for my company, but i want to spend a good amount of time choosing the cosset and fonts that i will use, the company is a modern IT consultancy firm (big difference between consultancy and 'repair centre') offering mostly commercial services to businesses and corporate companies, swell as the walk in home customer. I want something that really shouts professional. the colours are Green and grey, that i really have in mind the companies name is ITech Computer Solutions , I like the idea of some sort of binary overlay. but really ideally a fixed price, that we can both agree on.

Thanks
James
