ASAP -Easy Dolphin Adjustments

Have Dolphin installed, but looking for someone with sufficient programmatic experience in Dolphin to make some adjustments.

In essence, the site will be designed as a virtual platform for subject matter experts in particular areas of policy. I want it to be by invitation only, the content not searchable outside of the site, with a few adjustments (removal/addition of links here and there), all hints of 'dating site' like features removed, whatever else seems reasonable given the functionality, etc. I suspect the changes will not require a great deal of time/energy, nothing profound, but they do need to be made.

Will provide more details as necessary, I'm very easy to work with, just looking to get this done ASAP. Will pay upon completion of the work.
