Customize Dzoic handshakes

I am in the process of buying Dzoic Handshakes and am seeking an expert who is familiar with Dzoic handshakes to perform the following project modifications. I want to customize either the EVENT SECTION or whatever MOD of Dzoic handshake social network script to accomplish a similar functionality as [login to view URL];bid=10&cid=0. Basically, users or myself will be able upload (or post) flyers which will be listed in the event section. The flyers will be listed similar to how they are listed on [login to view URL];bid=10&cid=0. However, I don't want the identical view of [login to view URL];bid=10&cid=0. to be my default view. Also, only events that are paid for or approved by me (admin) will be listed in the public view section. I also want to modify the homepage. I am still working on how I want the homepage to look. How much will it cost for this modification and how long will it take complete? I don't want to waste your or my time and money, so only bid if you know you can do the project. I will have more modifications, but I will start with this part for now. Thanks
