Help fund my goal

I have been trying to get enough sales on my online store to be able to have an income but alas after 2 years I barely made any profit. I want to be a successful entrepreneur and would like to open a walk in store to enable customers to purchase, research has shown that there's a lot of skepticism in online retail due to various factors such as online scams, not being able to see the product before hand etc. I have been working hard on getting investors but to no avail they all want collateral and since I'm a single mom of 2 kids working whatever part time job I can get to make ends meet I have nothing to offer them. I have put in hours and hours of endless work into my store and I would like to make my vision of a walk in fashion store a reality. I would appreciate anything that would help me achieve my vision, I'm no longer following my dream I'm hunting my goal and I'm not going to give up till I get it. I thank you in advance for your contribution
