As there are many great answers to your question already, let me suggest you build your online presence/online reputation as it will support and increase the ROI of whatever marketing efforts you do. You can set up your Google My Business listing, set up attractive image posts for the bottom of your GMB, set up high Domain-Authority citation cites, ask for reviews and have video appear in the search results - all at no cost just by doing the work yourself. When a potential client searches for your business in the future and sees all of the above in the search results, they're much more likely to respond to whatever marketing strategies you're using!
