VDI server set up 70 users.

Before I start this please understand that I am an IT Enthusiast not a professional. Please dont hold that aginst me. I am about to build a new office building from the ground up. My dream is to have aprox 70 working stations. Simply monitor attached to the wall with keyboard and mouse all connected to a windows server. Running VDI or something like it. I dont want computers under desks. Please let me know if I am stupid for wanting this, ultra clean setup or not. If so where do I start what terms do I need to know so that when I talk to an IT consultent I can get my point accross. As far as budget that is an issue for latter. Again this is a ground up build. Thanks for the knowlage.
