I have a need for a qualified person to create Entity Relationship Diagrams (ERDs) from an existing database. Basically, I need to visually represent what we have in our database archtecture in an ERD. Organization will be by application module so there will be several individual diagrams that will include subsets of the overall tables in the database. There are roughly 2000 database tables. Each diagram will have 25-50+ tables (or more as necessary). The budget is an estimation and I realize - given the right person, this will be a longer term engagement. We have a need of documenting via ERDs, at least 300-400 tables as soon as possible.
