joomla designed website

looking for a web designer/programmer, graphic designer to add a new custom template, graphics and functionality to existing website or create a whole new website. current website has many of the pages already done with text but needs to be designed better with graphics to be more appealing and user friendly. for the home page i would like some javascript or flash to add some moving text which needs to be easily edited. as for the functionality i will try and explain as best i can. The website is lottery based and customers will select their lottery, select their chosen numbers, create username, password etc..,pay and then be taken to their own personal page where they can view their purchased lottery, edit details, withdraw winnings, purchase more lotteries etc.. Membership page needs to show selected lottery currently chosen, current amount won, points accumulated, numbers chosen. Each customer will also choose 5 numbers for the daily free draw and points would be accumulated by matching so many numbers. Member details, numbers chosen including free draw numbers will have to be recorded on some sort of database for easy access. payment will be done by a third party extension (if thats whats you call it) paypal or similar. Ive tried to explain as best i can, sites with similar functionality and the kind of design i'm after is www.national-lottery.co.uk. please contact me if you require any more information. What i would like to see is a breakdown of what work would be needed and samples of portfolio. with thanks
