Me and my friend are planning on starting a shop for speedcubes(Speedcubing - Wikipedia, the free encyclopedia) because there is only one shop for them in the UK(that is used) and it is badly run, orders take a long time to deliver, some don't get delivered, the website is bad, etc. We have contacted wholesalers on alibaba and verified them being legitimate. We also contacted a few us stores to ask how much money was required to start a shop. The average price was roughly 2000 USD. However we don't have much money to invest(~$500), how can we get the money to be able to start the shop and how can we advertise?
