No offense, but I don't think you want to think cheap for a trust. I am sure other may disagree.
It's worth spending a lil extra IMO to have a face to face service, someone you can call etc. I went with Brittany Stouffer who is now an IP. She did such a great job, the wife and I hired her to do a will for us as well.
Just my .02
What did that cost you for the NFA part if you dont mind me asking? I completely understand wanting to get it done right I just only have X to work with. If i can find an affordable way to do it that will still covers my butt id be happy with that.
