Design a classified ad module for Joomla 1.5

I want someone to build a classified ad module for Joomla 1.5. I want the module to function? exactly like the classified ads on this site... [login to view URL] ## Deliverables Just go to [[login to view URL]][1] and view a few classified ads. I want the module to work exactly as the classified ads on this site. I want users to be able to register at my site and post ads with pictures. I also want to have the option to charge money for the ads. I want to be able to create as many categories? and subcategories? that I need. Thanks.
