$18K and $30K??? wtf? no no no. I'd buy a product like Balsamiq and do the mock up / wireframe myself and then enlist a good coder from Odesk or Elance to add your features and do the back end stuff. But first you need to validate, find people willing to pay for such a product/service first before you do anything. If not you will spend all that money and invest all that time and it may never sell. That guy telling you $18 and $30K is trying to rob you, development for a simple saas does not cost that kind of money. Now if you were developing some large piece of complex software I can see that kind of money but not for something simple.
I hope this helps Carny
