This is not a good forum to ask "how can I make X vendors product cheaper?". It just is not good business. Im all about being thrifty, but Im also all about tact and good business practices. I recommend you start a thread entitled MOVING FLOORS- and ask how other haunters did moving floors or moving floor hallways in their haunts.
It is actually better for the industry in general to do it that way. Vendors can get ideas to sell to haunts who do little fabrication, and you could end up with a concept superior to your needs than merely duplication. You will have options as opposed to a copy.
When you start your new thread I will even chime in with a few ways that I have done moving floors.
