Cresha:
Why don't you contact Jacquemoe and ask her input of your lay out and if she would have done anything different since she has started her quilting business.
Your lay out looks great to me. Just make sure there are no shadows and you have plenty of room to move around.
As far as renting out your machine.....................I would get my business up and running and then maybe find a different machine to rent to the public. There is nothing more frustrating than to start using your machine and find the person who used it before you messed it up.
I wish you all the luck!! :D
