Im looking for a programme which will allow my customers to pick a window tint they require from a drop down list that I populate. They will then be able to add qnaitity of windows, the width and the drop of the window. They will be able to add as many varying windows as they require. The programme will then work out the best width and length of window tint they will require. I will populate a database with the window tints available, the available width and lengths that the window tints are available in. Is there a tool out there or is there something that can be modified? If not does anyone have any suggestions and costs for a bespoke tool?
