Sorry, I don't even have a clue what to call it. I am looking for a plugin or the code that can allow a customer to enter their zip code and then it will give them an automatic quote and order form, based on the zip. Is there anyone interested in doing this, quickly and for a reasonable price?
Similar to this:
http://www.rolloffdumpsterdirect.com/ First they have the quote box, then below that, the customer can also put in their order # and schedule pick up of a dumpster.
Thanks very much if anyone has any suggestions.

define a 'reasonable price'

Well, I don't really know -- what is reasonable for this? Why don't you tell me? I was thinking in the hundreds, not the thousands!

The zip code determines the price. So they enter the zip code and select the size dumpster they want, and based on zip code groups & size of dumpster, a price is shown at the top of the order form -- order form is always the same. The sizes are just a list they choose from.
Price is based on zip code groups, not price per mile or anything else.
The other one is they put in their order number and it retrieves their info and lets them schedule pick up of their dumpster. That is not as important as the zip code price search.
I hope that helps. I feel like there is some name for this kind of program and if I knew it you would understand. Oh well.
