Add-on JomSocial / Xenforo

[Dynamic]

Hello,

I am looking to bridge JomSocial and Xenforo together. I would like JomSocial to handle all the user data and pass it on to Xenforo.

I also need Xenforo to work as though it is part of the JomSocial program. This means that any alerts created in Xenforo (reply to thread, etc) show up in the JomSocial alerts. I need it to be compatible with Xenforo addons and have Xenforo retain user permissions for the user.

Can anyone give a rough quote on what something like this will cost?

Thanks.
