$100k is more than enough to start a business, however for what you have planned maybe not so, but if you play it smart you can find a way to make that $100k work for you. The owner from WCC started out his business with just $5000 and that got him pretty far today.
If i had $100k in the bank or even, i have no doubt in my mind that i can use that money to start out a business similar to yours, and im only 19. If you really have the ambition and passion to start out your business then you will find a way to make it work, even if you have to start out small.
You have great ideas laid out but honestly if you think you cant do much with $100k then i dont think your really ready to start out a business or run a business for that matter, all in all, take some time to think about your plans realistically, then figure out how you can get there realistically, Good look man
And keep it simple by the way
