I know it is too late for many but if you are ordering anything NEVER give a huge lump sum deposit. Honestly there is no reason for any company to take a deposit that big, they may buy supplies for the entire project at once but usually have them on credit snd most expense for projects like this is labour. Agree to a set of deposits that you pay as they do work on your project. This is harder if you are not nearby I realize that, but keep checking on progress, by pictures if you have to. If at all possible do your deposits by credit card so you have another way to go after them if the project is not completed. ALSO have a written time schedule that you hold them to and if they do not stick with it there better be a very good reason or you get your deposits back. I hope you and others get all their money back or the unit you ordered.
