High Margin Scalable Business

Hello you wonderful and intelligent people that make up these forums. I truly hope you are having a positive day and that everything is going well for you.

I was kindly wondering about new business ideas i was brainstorming about some new concepts. I was wondering if anyone had any thoughts on any high profit margin business models, that could be operated online, that dont require as much initial capital to get started please? The idea i can think at the back of my mind for instance is like if you was selling concert tickets online and if you can buy them when they are initially released online, the re-sale value can be 3 - 4 times the value you paid for them. If anyone please kindly had any thoughts on this it would mean the world to me and i would be forever grateful and thankful.

Thank you very much to all the amazing and wonderful people on these forums, who share so much amazing insight. Sending you lots of good wishes and i truly hope you achieve massive success with your business goals and continue to have a wonderful life. With my every best wishes to you. Very best wishes for the future.
