I just visited your website in different browsers and it is not displaying properly in firefox (please test in different browser).
One very important point! when i visited website using chrom, it shows popup occupied around 25% of space. Being a customer, it is distracting. I would recommend reducing size of the popup.
Apart from other suggestion given by Logan, i would recommend going for email campaign in your area. You can easily get leads from Yelp or other local website and create one email campaign explaining your services and offer some discount. If you have small budget, you can even go for lead generation services like http://aruhat.com/datacrops/lead-gen...ta-extraction/
and generate quality leads.
I have tested aweber and mailchimp which gives best result and leads for our business.
Hope it will help
