Unrusty

Hello, all! I was looking for advice on where I could possibly get 1/72 and 1/32 custom decals made? I am a flight paramedic and I have started to make some EMS helicopter models (specifically EC-135 and EC-145) that I would like to look like some services in the US. I can paint them up well, but I would like decals/transfers for the tail numbers and also logos. Any ideas how I could get some made up or make them myself? As an aside, I didn't realize there was such a dearth of civilian helicopter models. I would love to get the Bell 407 and EC-130, but I can't find them anywhere. E
