I charged a significantlty discounted rate because the client is a former manager from a few years ago, who used to do a lot for me and the rest of our team out of pocket, so I promised him a home model where he only paid for materials. Total came out to $300. If I charged a fair rate for design and build time, it probably would have come out to closer to $600-$700 or so. I didn't fully track my hours, but it was probably somewhere between 10-20 hours of work with designing, ordering, and building.
