Webdesign - General Admin Panel Web design (css based ) needed

Overview: I need an adminpanel webdesign purely designed in CSS ( tabless design ) and XHTML. There is no specific requirements on how it should be, but all the generic features normally available in an admin panel should be there. For eg: Top drop down menu, Side bars, one sample form etc. You may refer magento, sugar crm or any other cms / open source software to get some idea of how a complex admin panel look like. * I am NOT looking someone to develop from scratch. If you are a web designer with experience, you might done this many many times. I would like to get one of that as I don't have much time to develop from start. * I don't want admin panels ripped-off from somewhere. It should be your own work. * Should make use of javascript library ( eg: jquery, prototype, [login to view URL] etc ) * Should attach atleast one form design for each add form, edit form, list form. * If contains ajax support that would be great. * Should look professional. Should be compatiable with popular browsers. Having necessary icons will be good. * Forms should support error messages to be added along side of form fields. Layout should not broke if we add more text. It should nicely expand the layout. * If the admin panel design contains lot of features and complexity that would be great. I will pay for it. * You need to provide a demo by hosting in your server. * Will you be available if I need any change now or in future? Please make your bids with contact details, cost, timeframe and demos. If I am satisfied with your work, this will be a long term relationship and will give continuous front-end webdesign ( css based ) work. Please do not contact me without demos. Ask me if you need any clarification. Thank You John
