Lets say I buy $7,500 worth of tokens at $1.05 each, that would be 7,125 watts of energy worth of miners I would be entitled to use.

So, I have the option to either use a Bitcoin, Litecoin or Ethereum miner for up to all those 7,125 watts of energy can produce, I only have to pay the following fees:

  * Electricity
  * What other fees?  please state what other fees I would have to pay shall I were to make this kind of investment for the stated value here.  

What would be my total monthly $$ obligations to push 7.1 Kilo watts worth of mining?

Are there any fees to be paid even if I were not to be mining in any given month or time frame?  Say I decide to take a 1 months vacation (hypothetically) and on that month I do not mine anything, are there any fees that I would have to pay regardless, like maintenance, etc?  And what happens if I fail to pay any of those obligatory monthly/terms fees?  

And also, just for clarification:
Buying 7,125 watts of rights for the next 50 years automatically grants me access to any of these miners to use included with the purchase price of the tokens (meaning the mining gears are included with the tokens for the coin of our choice BTC/LTC/ETH), or would I still have to buy the actual miners at its full price and all what the tokens grants me is the right to use for 50 years an "empty" mining facility where free electricity is not included and I still have to purchase the actual miners on top of having paid the $7,500 worth of tokens?
