I am unable to start my startup because of its scale
ig1: Do you have experience in running this sort of project (i.e. for your previous employers, etc.) - if not you'll have a hard time raising funding just with an idea. There are a lot of complications from running this type of project, even when you have someone experienced running the show, so getting funding without experience is going to be close to impossible.Although if you have unique value only you can provide (strong relationships with large potential customers, etc) then you should focus on that and try and sell that rather than just your idea.I think the best route is to build a prototype one way or the other (learn the skills, partner with someone who has them) and you'll have a much better chance of getting investment.
