We like Entry #22. Could you please use 'Pine Trees' where you are using trees ? The company specifically uses Pine trees, and the company owner has requested their use in the logo, if possible.
Also, can you try a little more masculine, yet professional-looking font ? The general feeling, though not universal here, was that the font was just a little too feminine - though the rest of the logo looked top-notch.
Thanks. Excellent work.
