Hello Theo, How are you?
I need to develop a word press plug-in, which is essentially an advanced calculator. It needs to be able to calculate used car values just like [url removed, login to view] "http://www.kbb.com/car-values" I was messing around with it for a while, but i couldn't do it. I need to have a 2 separate list of makes (eco and luxury), each with a drop down, which then the user selects the model, the make, the mileage, the model year (2008+), a simple hidden current year which will be used in the formula and the ability to show forms. I have devised the formula, so you do not have to worry about that. It needs to be a bit simpler than kbb's but function as good? Could you please quote me if you are able to do this project? I will also provide you with all the pictures, a list of the makes, the models, and their prices for each model trim. It also needs to be user friendly so that I can manually add those through the plug interface.
I am also a Graphic Designer, so I will design any thing you need for the plugin.
