I like it, though I have a suggestion to cater to the confused, clueless, or non-wood worker type.
I would move the Mobile Log Sawing Service outside of the log so it is easier to read. Curve it around the log. Put the Mobile under the A and the "Log Sawing Service" curved around the bottom of the log.
That way your business "Log Sawing Service" stands out and is easy to recognise by people that might not know about sawing and the "mobile" by itself at the top would be easy for people to recognise as "you come to them".
Many people have heard of mobile windshield repair and might wonder what a "mobile log" is suppose to be.
My $0.02, less counting inflation.
