I'm on the same quest as you are,
just started prospecting a few days ago.
here is what i do, i focus on quality prospects over just prospecting to whoever.

I look for clients who show signs of interest in digital marketing but haven't been successful, in my case i just go to maps type in a search query "industry + area"
which industry?
all industries could make use of digital marketing and SEO services, but which ones are the best?
the best ones are industries where traditionally most businesses aren't relying on SEO but few businesses are currently taking advantage of that and ranking on search results with minimum effort, these few businesses are disrupting the industry by the way they are marketing.

i picked a business that has a nice website but doesn't rank for the main keywords, and now we are in contact, hopefully, i close him soon.

He already has a website that shows his interest in digital marketing, so he is qualified.
I think you should adapt this to your prospecting process.

as an SEO specialist, there is a clear need for Web Design and it is much easier for someone with experience.
the amount of businesses with poorly designed websites or no websites at all, is huge.
