Create a post with your products and include the price (plus shipping). You can even create a separate website/blog to showcase your products. (:

I am doing something similar for my public relations work and will advertise it here to the steemit community. Check out Hive account@steemgigs also maybe you can advertise your products there!

Keep me posted and let me know if you need any help (: i can help with web design, marketing and social media!

Good luck!
