I've never used foam before but I do know the material and they can't be prototyped the same way plastic parts can. What you're going to have to likely do is have them milled which will raise the cost considerable. Look for a local shop in your area, they are all over the place. If you don't have a time constraint you should be able to negotiate a lower price.
When you say 'small run' how many units? Part size? How many variations. If the quantity is large enough you can have an single mold produced with each part variation. While you will have extras it'll drastically drop the per unit cost. Most of the cost is the mold and setup (fixed costs), the materials cost next to nothing (couple dollars/pound).

The size envelope is like two stacked pack of cigarrettes (obviously there are holes for the electronics and for the phones to be stuck in). I don't know the number of units or of variations yet. Once I have a working prototype and software my plan is to start a project in my local Kickstarter-alike which would tell me how many to make and, just as importantly, for how many different models of phones. Oh, and right now I am building the prototype the old way, with sheets of the material, x-acto and glue. CAD/CAM software and milled prototypes won't come into play until I have something that works. Then I will start trying to price the production. Right now I was just taking advantage of your offer to share your experience. Thanks again.
