Don't waste your time with the frames. Buy new ones. Buy them as you grow so figure what you will need for the following year for your increases and buy that amount. Deal directly with Nick at Pierco and you will save yourself money. Go through the boxes. Anything not tight get ride of. With 2500 you have lots to choose from so only choose the best. You are going to want to go with pallets as soon as you can so see how much work it would be to pull the bottom boards. Hopefully it won't be too much work. Where you will really save starting out is with the honey house equipment so if he has that you will be way ahead. Even if it is galvanized you can clean it up with a pressure cleaner and hot water.
Good luck.
