I have been a database programmer for over 20 years with the last five years devoted exclusively to Access, Excel, and VBA. (See my resume for details.) I do not program games, general desktop apps, or web apps. I specialize in one thing: Excel/Access.
1. Are you asking for a read-only database to be copied into a read-write version? Is there any sort of copyright issue here?
2. If you're asking for a rewrite (or a copying), are the tables visible and accessible?
3. I'm not concerned about answering any questions you might have. I've taught Excel/Access nationwide. We can use any sort of online messenger service, and you can come onto my machine as we discuss whatever.
4. Depending on your answers to my questions (or my seeing the database per se), the bid could go up. It's all a time issue to me.
Let me know.
