No Money Tree

So its been 3 weeks and nothing has been changed or built, not one nail.  I had to send blueprints back to the engineer to correct a mistake not caught by the contractor, which took 2 weeks, Now I am waiting for a new bid to finish the job, I'm going to keep this short, because if I start on my soap box I may never get off.  Lets just say this,  THERE IS NO MONEY TREE.  I not sure why my contractor thinks I have some secret money source when the original budget was going to stretch my very limited resources.  Now the contractor needs way more money to do the same job he already started.  This is so frustrating.  If someone has a money tree please send me a seed.
