I'd definitely recommend that you call up Andymark. They have a phone number listed on this page here: http://www.andymark.com/Contact-Us-s/177.htm You should be able to speak to one of their engineers and they'll help you spec-out everything you need from their inventory for a one-stop shopping experience to finish up this project.
