As far as cost for the program to be developed as well as a software program and scanner I can say it is going to be a costly sum but the pattent will make it worth it in the long run. I do not intend on charging a retared sum of money for this service either. Try to stay at or lower than TPG's now. The hobby will appreciate it more and in return the dividends may be small but will add up over time. Steady wins the race
