Joomla + Classified Ads + Forum

I am looking for someone more experienced with Joomla and PHP to setup a site for me. I already have the host: dreamhost, domain name is still missing/not decided. The site should be based on Joomla, have extensions for classified adds and a forum. User account creation should be only with a screen name and password. Users should be able to post in both the classified address and the forum. If possible, there should be an option to elevate the access level needed to post in the classified adds and to access that level a payments would have to be made (paypal). It should be possible for me to easily add geographical areas and cities to the classifieds catagories. It should also be possible to add several selectable fields, which all can be searched on. It should also be possible to upload up to 5-10 images per classified add and these should be displayed with the add also. Most importantly classified adds should expire after a set timeframe, which should be adjustable. An example of the layout is attached. I have already found the joomla in combination with extensions AdsManager and Agora, this should be possible. But, some features and function would need to be modified to suite my needs. I figure, that since I could easily already do most myself and get it working, that this should be a small project for an experience Joomla and PHP person.
