First, congrats on making 5 years. Many in this industry don't. A couple of thoughts for you. I'd recommend that you send out flyers. Not a handful, but 3-5 thousand. There are business that'll deliver them for you. If you gotten a good amount of business from word of mouth, then offer a referral program for your customers. Do a search on referrals, there are several ways it can work for you. Good luck.
