looking for a designer that can help setup our WMPUDEV Membership plugin

We need help getting our membership signup process fixed. we have 4 subscription levels and use the authorize.net gateway. having trouble getting the right pages to show during the process and been ripped off by 2 people who said they know what they were doing. Any suggestions? This should not be that complicated as most of the work is done but we need someone that knows the plugin to help connect the dots.

or can you give me a reasonable estimate of time that it should take someone that knows what they are doing?

thanks!
