This forum is here to help people learn about car audio. I realize you offered to pay someone to design your box right off the bat but in most cases on here, people ask for help designing a box and the first reply they get is "pay someone to do it" or "I'll do it for $15"....I just don't see how this is one bit helpful. If you think you should be getting paid for your services, open up or go to work for an install shop.
In some cases it may be more difficult to design the box but yours and most requests on here are pretty straightforward, you know the volume and tuning frequency you want or they are specified by the manufacturer. It doesn't take much more than 20 minutes to calculate the dimensions for one of these. I often see a few of the people who charge for designs logged onto the forum for hours on end...it is pitiful that they can't take an extra 20 minutes to help out a fellow car audio enthusiast.
