Creating custom user groups and integrating PHPBB in forum

I have the registered version of JUGA (Joomla User Access Group) program installed on the website. I need to have an expert integrate the already installed PHPBB forum with JOOMLA and also to create custom Joomla user groups using JUGA for the different membership levels of the website. I am also interested in setting up an automated payment process, but this is not part of this project and it can be a potential second project once this one is completed.
