Becoming a promoter
You don't need anything to sell yourself to start promoting.
Anyone with an ProdLinc account can apply through Become a Promoter, a short onboarding flow separate from becoming a seller, that doesn't require you to have anything to sell yourself.
Once approved, your promoter dashboard is where you create and manage links, separate from the buyer marketplace you started in.
You can be a promoter and a buyer (or seller) on the same account. The roles don't conflict.
