If you want to create such a project and want to launch a Bitcoin system to sell your goods, then of course you can do it. But I think that launching a Bitcoin payment system will not inspire many people here, very few people can be inspired by it. Although I have not purchased any product through Bitcoin so far and I do not have much idea about payment systems. But I have seen a video where a lot of discussion has been made about payment systems and from there you can take help if you want. I am sending you a video link on how to launch a Bitcoin system and how it works, you may benefit a lot if you watch it.
