To follow on what bomo added: Kit Car magazine or Kit Car Illustrated did a story (series actually) of budgeting and planning a project.
They even covered tools and consumables.
Addresses are www.kitcarillustrated.com.
I thought it was well presented and honest writing.
My personal opinion is that you should start with a completed or nearly completed project instead of beginning at ground zero. There are plenty to pick from no matter where you live.
Good Luck with your project!
