Expert support for filemaker pro advanced

I am building a Filemaker Pro application and I don't have that much experience with FMP. I am looking for someone that can work with me online to help me build what I need to build. I would like to be able to audio chat and regular chat to help me with my issues in real-time. Here is one type of problem I am looking for someone to solve: I have a table called projects that lists of all the projects we are working on. In that table I have a field called "artists" and a field called "supervisors". I have a second table called "contacts" that lists all of the artists and supervisors and all of their information. When I look at a project I want to be able to see a list of all the supervisors linked to that project and also a list of all the artists linked to that project. On that same page I want to be able to add new artists and supervisors from the contacts table to the project. One project can have hundreds of artists and supervisors and also a contact can be linked to dozens of projects. How would you design this?
