My first commission is done the style and method will be refined and fine tuned as i go along find suppliers and adjust but i like the prototype here is my website http://bpbloodmoon.angelfire.com/wolfpackmods/ i do more then just ventilation systems i can also wire in lights make glow eyes ( depending on the current eye style) and other neat stuff if you have an idea of what you want but are not sure how it would be done or how much send me a note card and i will research it and give you an estimate
