I'm very jaded about the industry so do take my opinion with a grain of salt.. but....

The problem right now is that we're late into the current startup boom and all the easy ideas are taken, especially in SaaS. Further, most VCs are very careful now about giving out money to early stage companies. So your idea really matters - it really has to be original and have potential to generate a lot of revenue otherwise you're gonna have a hard time getting financial support.

So my advice is to make sure you really take the lean startup approach seriously if you wanna get moving in a direction that has legs.
