That being said, I agree that any good GC will be able to do either of the projects you outlined, I would love to discuss your perimeters further to see if I can help with a contact. Let me know if I can help you work through this process, it can be tumultuous, and having people in your corner is never a bad thing when it comes to finding and vetting contractors.
