I’d definitely set up a small website for your business if you’re trying to spread the word and get more visibility.
You could go the Wordpress route and do it all yourself for cheap if you’re a bit proficient in that type of thing, or you could have a custom site set up for a reasonable amount by a freelancer.
After you have your site set up, you can spread the link around, put it on a business card so anyone interested can go to it and view your cake ‘portfolio’ so to speak, etc.
If you’re interested but need some help from someone who does websites freelance, feel free to message me.
