Ask your one client for referrals. Get google my business page and ask them for a review. Post regularly as other user said.

Also, figure out where your community talks. Online forum, Facebook page for your town/county, local meetups? Post on those online forums and go to the local meetups and ask other people what they do. Be pleasant and make a great impression by keeping the conversation on them. See how you can give them value and then let them know you have a cleaning business.

Don’t be afraid to ask for reviews and referrals as you continue to grow.
