Contact Form with Flexi Content ?

I would like 2 populations : announcers and public
- An announcer register on the site, publish all required informations to construct his details in the site directory.
One of these informations is his email used in his dedicated contact form (which hides his email to spammers)

- The public browse the directory and when he wants to contact a company he use the announcer contact form

So there should be 2 kinds of forms : the submission one with registration (and payments for optional fields) and the contact ones to send informations from the public to directory customers

Depending on Flexicontent capabilities, the contact form could be the same for all annoucers, or customised for each.
Thus each Joomla article should refer to the contact form type and to the destination email.

Are my explanations more clear ?
I would like to reproduce Listbingo functionnalities.

You want to have fields that are available only to specific users?

We have not added yet the "editFieldValue" permission Action, to allow specific user groups to use(=edit field values) after e.g. paying for it.

The idea is that user pays with a third party payment/subscription component e.g. AEC, the the user is added the user group: allowDetailedEntry

users belonging to the allowDetailedEntry user group can edit field values for fields e.g.:
- websitefield
- emailfield
- field45

people not in the above user group , will not be see the fields in the edit form
