Hi, I planned to run a Service based SEO membership.

I have been checking amember and easymemberpro. Those member management script are more suitable for content based membership.

Can anyone recommend me a more suitable membership script for service based?

Like:
I can interact with the User?
User have their owned private dashboard?

Use Butterfly Marketing Open Source, it will be very useful for what you want!
I used it myself. And is FREE!

what about wish list members

I would suggest you do a Google search for "the best membership scripts", and I think there are a couple of good scripts. Anyway, I would not go with any of them, but in my opinion hire a freelancer (a cheap one you can find anywhere - there are people from india very talented that work for a very small profit) and built your site.

To your success

I use easy member pro for mine and with a little bit of customization it fits my needs.. but then in the future i am looking for something else (most likely custom) to handle things a lot easier.
