I'll make some recommendations.
These charts seem to run on 24 hour cycles. You might want to make note of that in your promotion of this. You might want to tell people that you have a 24 hour period where you want to really push hard to get the song on the charts. If you have 5000 people willing to buy the song over a week, you don't get on the charts. If those 5000 people all buy in the same 24 hour period, the song does get on the charts.
You get them to buy in that 24 hour period. And then you PUSH when it appears on the charts. You will want to have a fairly detailed idea of what you're going to want to do when the song does hit the charts. Remember also to look at the genre charts as well. The plan should include screencaps, etc. My own personal plan is to spring into action when I see the song on the charts and the hype that goes with it.
To this point, I really can't tell if this is something that 5 people care about, or 5000 people care about. Based on looking at this,
http://goldenstateband.com/ Golden State's official website, and this
https://www.facebook.com/GOLDENSTATEBAND it doesn't look like this is the top priority of Golden State. Which makes me think more highly of Golden State, but less highly of the eventual success of this project.
But that's not criticism. I'm not negative about this at this point.
