I need something like this on my site.
http://www.dekaltrim.nu/designer.asp
I need it on the product page so customer can write there own text and choose font, size and color. It also need to calculate price depending on size I also need to change the price. It also need to have three text rows, that one I linked have only two rows. If you choose width it has to calculate the height automatically and and if you choose and if you choose height it will calculate width automatically. I need to add fonts and colors by my self.
Can you tell me what it will cost to do this?
