Web Designer

I am looking for someone to produce top looking designs for my company. You must be an expert at design and have a fantastic portfolio to show me. Designs must be made and approved then you must convert to 1 page. No limitations on what you use, ie JQuery must be used if it will make the site look nicer on banners etc. I am looking for someone who is flexible and can provide a few designs for me not someone who is unflexible and wants to charge extra for things. The intention is to pass 1 website per week so cost is important. you therefore need to produce designs fast (in 1 day, with conversion) to be able to bid at a cost of around $50 per design. I do not want a company with more than 1 person bidding on this. This is 1 on 1 project so I want someone to work with me 1 on 1 thats 1 person ) to strike up a long term relationship with with the possiblity of passing $500 worth of work per month. Again, I will stipulate 1) do not bid if you are a company with more than 1 person 2) you must be flexible and not require extra money for small changes or using extra things like jquery 3) you must be a nice person and available on IM gtalk/msn/skype THanks
