Customization of a social networking website

I purchased the social networking software (Handshakes Professional) and I? have the script already installed.? I need someone to customize the look of my site such as creating a new theme for the welcome? page.? There are only 2 themes I can use right now and I dont like either of them.? Also I will have to give access to the admin area so I can get all the other things changed as to my liking.? I have enclosed the zip files that states what an admin has to do in order to customize the website.? ? It's a fairly simple job, it's just I don't have time to read all the details and edit everything required.
