classified template

I have a Joomla website that is used to sell and also allow free classified ads. I need a template altered to work with the site. the site is fully functional and does not need any work apart from changing the template to work with the moudules, I can provide details of postions etc. I have a LOW budget so please no silly quotes. I would like to get this done asap. I would also like a good sef plugin adapted for the component.
