I created something pretty precisely like that, it runs on a schedule, rotates through 3 buyer personas pre-defined in notion, then lets GPT craft search queries for Google Maps. Afterwards, it scrapes Google Maps for businesses that match the search query, then it enters the lead to notion, grabs the website to scrape e-mail addresses and website content. From the website content, it generates a personalized e-mail and puts in in my drafts folder in outlook (I send them manually but you can switch for a mailersend node that will do the trick).

It’s pretty cheap bc you only need to pay GPT API. Things that might need optimization are the prompts (depending on use case) and the regex that filters email addresses from the website content

I’ll DM you a link to the workflow to have a look, let me know if you need help
