It’s really hard to share my thoughts on your new business, because I haven’t got a clue what you sell!
If you’re selling your own product, I think you already have an integrity that most influencers completely lack. Likewise you know your product and truly believe in it. This is the holy grail of influencing. This gives you a head start as a lot of us really value and support small businesses.
Regarding confidence, see it as a job and you’re the CEO. Essentially, you can then put on a work coat and play a role, where you can be a stronger, more confident version of you.
Really push being a small and independent business, use your locality, ingredients etc etc to give your brand its unique identity. Emphasise your knowledge, maybe you have decided to create your product because you couldn’t find it anywhere else, or it wasn’t ethical, too expensive, poor quality, high carbon footprint etc etc.
You can even choose to be a quirky, fun brand if it suits your business. Who is your product for?
Only very successful influencers are paid in money. The average instagram influencer is essentially paid in products in exchange for a review. If you go down this route be careful not to cheapen your brand. Choose people carefully. They need to bring more than a single (not necessarily authentic) review.
