Where did you get the money from to start it? No-one's going to buy anything from a startup that does nothing, and doing anything means at a minimum some labour (and usually buying some stuff as well). Unless you're very well-connected, if you're not investing yourself why would anyone else do so? If you happen to be wealthy already then great (I suspect most successful startups are founded by children of rich families), but if not your choices are either spend time acquiring money to put into it, or use the money/credit you have.
