Build Form on Joomla site

I would love to make the "get a free estimate" form like [login to view URL];project=12&buyTimeFrame=1-6%20months&statename=IL : and the step 1 step 2 would just keep on the same page (wont open in new browser or change page). the form submission button will say "submit your project" and they will get a pop-up saying " you have successfully submitted your project, Expect a pre-screened professional to contact you shortly." So on the one form will be the contact data that is on the other sites "step 2" form that we will just have on our form, then all the trades we will just put in a drop-down box to save space. Under the trades list there should be a field for adding specific project details. It all should be able to fit inside the forms background image attached to this post. Let me know if you have any questions. list of trades that will be in a drop down box are below. FULL KITCHEN REMODELING PAINTING, DRYWALL POOL WINDOWS WINDOW FASHIONS SIDING ROOM ADDITIONS HEATING, VENTILATING AND AC BASEMENT REMODELING PEST CONTROL ROOFING LAWN TREATMENT DECK BATHROOM REMODEL FLOORING CARPENTRY TRASH-OUT Let me know if u have any questions. I need done asap, Barry
