Fully agree with what was said before - despite what you might think, your idea is most likely not unique, and most likely not the final version of your business model. Moreover: the more you talk about it with people, the more you will be able to finetune your idea and get one step closer to success.

Make sure you have a clearly defined target group (no, "women 20-30 years old, breathing" is not qualifying), who will find your offer irresistible, and that you know how to reach that target with marketing as this will be behind 90% of the reason your company will succeed.
I can help with that :) Happy to jump on a call if you wish.
