1. Its best to create a table for each category (Contractors, Sub-Contractors, Contacts).
2. Make sure each table has a key field that is unique.
3. Decide which table will be your main table. This table will be on the many side of you "one-many" relationships.
For example: if projects is your main table, your first relationship would be a "1-project to many-contractor", "1-project to many-Sub contractor", and a "1-contractor to many-contacts" relationship.
The parent would be able to write to the child and allow you to add more than one contact.
