Pro versus do-it-yourself is partly about the products used... but also about the Pro vs YOU ! I know people that have jumped into the business that I wouldn't allow order my dinner ! NO REFLECTION on Kali at all. I am actually referring to a personal friend doing this for a living... and he is an idiot although fun to hang out with.
I don't care if it's an auto mechanic, lawyer or webmaster. A business card means little to me. If you are gonna pay a pro get lots of references... besides his friends. And find out what he is using and do the Google work on the products too.
Guarantees are ok... A JOB WELL DONE THE 1ST TIME IS PRICELESS !
RIDERS - Just a bunch of guys that wanna go riding !
