In this section of your website, you can list your services. Each can have a brief description and link to another page with a complete description.
Tell your customers what areas you service. Do you travel to your customers, or do they come to you?
Do you run weekly specials? This is the perfect place to show off your specials. Contests could also be in this section. Run a contest to get more followers on your Facebook and Instagram accounts.
Show customers how to purchase on your website. Maybe have a "How To" video. With so many people being new to buying online, some will need extra help.
