I am having the same issue here, we have 900 sq ft and are constantly full up. Our problem is that we don't have a door wide enough for a pallet, so we have to box everything and then stack the pallet the day of and have it sitting outside until picked up. Moving to something with a loading dock or at least a garage door in the current market is going to cost 3x what I'm paying now.

I think I could stay in business just barely with the current metals prices, but would have to hire a shop manager since I still work full time as well.
