May I make another suggestion for you to consider carefully?
I agree that you have found something which people on this forum will say is a good business plan. But we are biased! We would be interested!
It will be important for you to get an accurate idea of how your customers will find you, how you will find them, how much they will trust you, how much they will spend, how many customers you will have by the end of each of the first few years, how often they will will come back, and how you will pay for the (inevitable) complaints and 'returns', how you will pay for the 'start-up' costs and running costs (business premises, power, insurances, wages, taxes, licences, advertising) and how you will finance the initial stock.
I'm not asking you to post any of that information on here, I'm just offering you a few business matters for you to check, just in case you haven't thought through any of them. We wouldn't want to see anything go wrong for you!
Good luck!
