Nice clean look. I think your image is very powerful. Also, the site is mobile friendly and that is huge in that almost 60% of all searches are done on mobile devices.
I would suggest making your phone number larger and more prominent. It is also a good idea to have a clickable link for mobile phones so they can just click and it will call your phone instantly.
I like to also give them a contact form with some kind of incentive (bonus, coupon, discount...) to fill out the form and contact me. I do it kind of like a survey so they fill out a few "non-threatening" items first just to get them committed and started. I feel like if I can just get them to start it will increase the chances of them actually following through and completing the form.
You can see my contact form and mobile phone clickable links on my website
