custom made cock box

So ive just finished building my first cock box, will post some pics later, I had a friend come over and we tied it out and he said he would pay me to build his box. I do really good work and very hot looking, what should I charge for a basic cock box? how much would someone pay for a nice cock box? I run a adult online sex store that sells femdom related toys and was thinking of custome building them and selling them. any thoughts on what I should charge?
