I would dump the "Sweepstakes" as it brings in to play a variety of state/federal laws and requirements that you probably don't want to deal with. And then there are the Facebook guidelines you aren't following.
FB would be my biggest, and most immediate, concern because if they suspend your page you will be thrown in to trying to communicate with a company that is only rivaled by Google in terms of the 0.001% chance of dealing with actual non-sales human beings.
I know lawn & landscape marketing, branding, and web strategy. I'm not anonymous, I just don't self-promote.
