Create clasifieds website on osclass platform

I need someone to "adjust" osclass platform to my preferences, for creating a classidieds website. This includes modifying existing modules and adding 2 or 3 new ones, in order to make osclass platform look and work like [login to view URL] website, but in english and with another firstpage map. There is a very similar theme for osclass called "firstthinkig", but I couldn't find it anywhere to buy it, as it's really close to what I want. So if anyone has it or can find it it should be really easy job to do. I mention that I only need modules and buttons to work and in position as all the design will be made by me.
