1. Make the pricing clear
Please, whatever you do, do not ask customers to contact you for pricing if it is not necessary. People HATE this!
If you have general prices that you charge for your offerings, state this clearly on your website. Or at least give customers an indication of what they could pay if you run a service.
This will help them in their decision making. It will also show them that you know what you are doing, you are a professional operation, and you are not trying to scam them in any way.
People are skeptical about businesses which are not forthcoming about their pricing.
