I personally have no intention of scamming or taking the BTC and running or such
That's the first thing a scammer would say.
But what makes you guys believe that? how do I generate any trust?
There is no "quick" solution to this. Trust has to be earned over time, and even then there are no guarantees.
Also, an operation like this would require experience. Someone who just learned about BitCoin should not be starting a large mining operation as their first endeavor.
And lastly, you would have to compete with the current offerings, which is tough, because there are some really good ones already out there.
