This is a great response, thank you. Unfortunately for me, it's unrealistic as we simply don't have the budget to hire all these people.

I see a future over the next couple of years where I have someone great in each of those positions but it will be a long, hard journey to get there.

This whole thread has given me a lot to think about and I wish I could personally thank everyone. However HN is limiting my responses so it might take a while!
