Hybrid ID-Contractors

Hi all, starting a new thread as I couldn't find one dedicated to ID-contractors or contractor-IDs.

Found a useful writeup on this breed of firms! Apparently, they are the ones executing the work, and can also produce 3D renders and basic design services.

Right now, we are rather inclined towards engaging one because

1. We are quite settled on the general design of the home.
2. After all the stories we've heard about how some IDs have gone MIA after signing, and left you to do the project management yourself, we are thinking that engaging an ID-contractor firm would help to cut out the middleman and allow us to work directly with the executors to translate our ideas into reality!
3. Heard about how some IDs charge high markups on each quoted item for the coordinating effort, and we are hoping that working directly with an ID-contractor would help to reduce costs.

Do you agree with our reasons?

After some searching, below is a list of some firms that seem like ID-cons (though it's not exactly clear, as some of them label themselves with various terms). Grateful for advice or experience with any of them, or if you have any more to add!
