Don't you just love growing pains?
Just a couple of points:
Be careful promoting your best worker to sales/ oversite or you could lose a good man. It takes special skills and mentality to do sales.
I would try to determine what you personnally like to do most and then plan to deligate your lesser duties.
I believe you are ready for a full fledged salesperson. Someone who likes people contact,is experienced and a self starter.
They do not need a lawn/landscape background as much as a strong sales desire. You will need to train he/she about how you do things anyway.
If it turns out that you love sales, then find a good operation guy.
Good luck, Gary
