I can appreciate your thinking. Some time ago I gave up a few hobbies and usually bring my lunch to work to save every penny I can to have my rifles custom built. Sounds like you want to have a rifle that is truly your own, and I tip my hat to you. It no doubt adds to pride of ownership to have your own sweat in it. I should also add that I am too chicken to build my own.
You already have a lot of good input so I'll leave it with giving a +1 to those who said starting with a trued action is a good idea.
