Okay, well, that's probably the problem then. Get a website. It doesn't need to be complicated, but just something that looks professional, shows your company logo, examples of what you make, lists a business address and links to social media accounts.
Make sure you have appropriate [name]@[businessname].com email addresses to email from, with email footers with your logo, links to the site and stuff. Have a linkedin page, have social media accounts for your business.
People aren't going to take you seriously if you don't seem like a legit business when approaching them.
