Starting a plus size shop in singapore !

Hi, i am a 29 year old singaporean who is looking to open a retail plus size clothing store. As plus sizes can be hard to find in singapore. As i myself am a big size guy. I come off from a poor family. And i have been trying to find ways to improve my life conditions. And im hoping that this attempt could turn my life around for the better. I have been contemplating what kind of store to open. And this idea was given to me by my fiancee. I am opening a store that sells plus size ladies lingerie and clothing and dresses and jeans. And a section for mens jeans as well. I am looking for funds to open a plus size store which i plan that can last for years. It will be able to cater to all ages. I will also implement an online store for ease of transaction. So please help will ya?!

Thank you so much !
