New Member in need of advice and directions

Himy name is Tom and Ihave been a machinist for over 30 years!
finally I am getting ready to open my own small shop! I would like to
be able to do my prints on my computer, but first I have to find and
learn either CAD Basics or auto-CAD, whichever is easier to learn!
Now my problem is I can't seem to locate anywhere near me that has
either program!Could someone please send me a URL or snail mail
address for a supplier who handles these programs? I am tired of
sitting hunched over my old drafting table trying to design things!
Thanks for your time and I would appreciate any help you could give
me!
