Congrats on starting your brand and employing your first employee!
I love the concept of your brand, and the clean & recyclable & eco-friendly look and design.
I would start with 3 things at this stage:
1- Targetting small, natural niche store owners on Facebook (find Facebook groups for natural products, beauty, and health), start communicating with them without being pushy, let them get to know you and your story as well as your products. You will need to create few structures of wholesale prices, first structure is distributor prices which is the lowest one, this may be not for the store owners, whether they have actual offline stores or online stores, the 2nd level is store owners prices, with the last one you want to make sure your wholesaler is making some good profit, by looking at your retail prices, I see these are ranging between $4-16, so I think selling to them at wholesale should be at 40% margin, depending on your cost.
2- Start get connected with dentists in your area first and give them freebies, let them test and promote your products, you may have to spend some fund on giving our free samples to the dentists as they can be excellent for your marketing strategy.
3- Get on social media, mostly Instagram and Facebook groups, find micro-influencers in beauty and health niches, possibly send them free samples so they can make videos and talk about your products, there are some sites that post these influencers and their engagements so you can pick good ones at the lowest cost, I wouldn’t spend much paying influencers at this stage, I may pick following and unfollowing on Instagram initially, following people who care about their health or people who are followers of some good size of accounts that are in natural health type of page. There is so much to talk about on social media and Instagram that can work really well. It takes time, right now, builds your followers, keeps them engaged.
