new site help.

I just started a new site and looking to get most of it done fast. I have it installed but I am already running into an error when I add a payment plan to the membership. I am looking for someone that really knows what they are doing to see what I am doing wrong and help install the mods I want to add.  The website is katynightlife.com Please msg me if this is something you would like to do and we can talk about price and what all I need. Thank you
