Looking for Membership / Director Plugin Advice pretty please

Hi There,

Long time reader, first time writer.. I was hoping someone on the forum could give some advice.

We require a plugin for a membership directory site.

We currently use:
Thesis
Gravity Forms

We require a plugin that will allow people to become a ‘member’ of our site on a free, trial or paid plan which allows them to:
1) create a profile page (enter info and add a picture that will upload info so all profiles have same look and fields)
2) auto bill them via paypal
3) all members have their own standard contact form (when visitor sees their profile and fills it in it will email them directly. Built with conditional logic e.g Gravity Forms)
4) paid members can edit this contact form add/remove questions
5) Can have multiple forms (contact, feedback, quote request etc)
6) members can login to see details of their own completed forms
7) members based on their plan can see secure pages, forums etc (later on)
8) visitors to the site can type in member names to find their public profile on our site (bonus if they can also search on their specialities listed in profile)
9) profiles are very SEO friendly

Does anyone have any advice? It’s for a business directory but I was even thinking maybe some sort of dating plugin (which shows profiles) might be good too?

Would love ANY help! Thank you so much x
