I'm going to give you some friendly advice so you can gather more business, i truly believe you have the customer service skill to get more business then you currently get.
1.You have to invest money to make your business better.
I see no
sign of that with your current setup. Get a tiny business loan - even like 5-6k.
1. adtechia.com <--- that website is godawful. fix it. As a consumer, I would auto ALT f4 out of my browser when your site loaded. Your town is pretty small, and I see no reason why you can't service a large chunk of your city for
sign needs.
2. a Legible clean logo that represents what you do
3. If you can't do it, outsource it - Don't make your customer be a test dummy. (installs, design, etc.) There are a ton of vendors on here who can do projects for you, and you can still make a heavy profit on it.
4. As much as people want to believe it works -- direct mail post cards go right in the trash, don't waste your money on it. Try other forms of advertising. Go out yourself and do more sales.
5. Typically Brokers can afford to charge a little more because, they deliver everything to their clients. Make sure you add that into prices - your time is money..
even if you just fix your site, pay a bit to have someone design it..
It will help greatly.
