Modern builder recommendation?

I have a modern home design that I want to build in the Spicewood area.  Unfortunately, the architect we hired is from Colorado and not familiar with the local builders and process.  This will not be a primary residence so cost consciousness is a top priority. Anyone out there have a recommendation for a builder I can begin researching?  Thanks for your help.

Kelly Ramsey has done an amazing job on 2 homes. One I sold to my clients and he's been adding a 3rd story for them. Another he just built which is up for sale.  Highly recommended.  He's very involved and hands on, my clients are very happy with his work.  His # is 512-762-3295.  Current home for sale is on Eagle Cove in 78734 so you can check out his style. Hope this helps!
