Depends on the size of hoop preference. Amazon has a good selection like this [https://www.amazon.com/Small-Wooden-Embroidery-Pieces-Darice/dp/B01LWCF3JX/ref=pd_ybh_a_15?_encoding=UTF8&psc=1&refRID=88PP8FG23NSS9BDJT99R](12-count 3 inch hoop), then create for less has [https://www.createforless.com/Darice-Wood-Embroidery-Hoop-6-in/pid145339.aspx](a good selcetion like these). I'm sure you can find some in there with what you need.

As for pricing, I think you should look at other creators like in instagram and see how they charge. I say, price it as how you see it fit. I think people who do not do handmade work and know how much work and love is put in each piece are the ones who complain about how much these handmade things cost. Do not undervalue your work, if one complains, easily explain your reasoning why you've priced it as it is. :)
