I'm far from an expert on SEO, but essentially Google is just trying to predict the most relevant results for people. To be the most relevant result, you've got to be the likely thing they are looking for.
Is it possible that you start ranking organically for "DJ" in your area? Certainly possible, but I think you will get much better results from treating your marketing effort like hand to hand combat. The likelihood of you convincing Google to show your page over something like WeddingWire or The Knot's DJ pages when someone types "Wedding DJ Waynesburg PA" is low. It is literally their business to rank high on stuff like that. Can you do better? Sure, but it's a matter of effort for return.
I'd pick an event or two where you can go and introduce yourself and hand out some business cards. Go to a chamber of commerce event, a BNI group, if you can find something industry related that's even better. But most wedding industry networking is going to happen after the busy season which if your area is anything like mine is right now. So I tend to see wedding vendor networking take place in January - March.
Make sure you're on instagram, weddings are a visual business. Follow
wedding planners in your area. Like the stuff they are posting, and comment from time to time. See who they are following and follow them too. Most planners tag all the vendors at the events they do. Make sure you're posting some wedding related content on your own insta and hope they follow you back. If they do send a quick note like "Hope you're having a great season, I'd love to catch up for a coffee when the rush dies down." - They don't know if you're busy or not, look busy!
As a side project you're limited on time, I know that. But you'll have way better luck driving traffic to your site through those initiatives rather than hoping Google will give you a boost as a small business.
I agree with Taso's comments about your site as well, there is some room for improvement there. But even if your site isn't the best one out there, if people have met you, interacted with you, like you... you'll keep driving results.
