I would like an application that prices signs based on certain parameters, most of it is just basic conversions and addition calculation. After calculations the application must run the client input data through other pricing calculators. Showing you our price and the same thing at another store. (based on what their pricing parameters are). Here is an example of what I mean in the link below.

I will develop this application in PHP using MySQL as a database to store all the parameters for calculations and to store also the results history for your clients. See also your PMB.
