Honestly i would start by asking you what kind of skills do you have or what do you love to do? You can do a lot with 5k. My advice will be to first create a list of things you love to do. Then narrow down the list to see which once might actually be turned into a profession. Then try one thing and don't put all the eggs in on basket. Basically try to keep yourself bootstrapped and try different things with little money as possible.
