Wouldn't bother with wooly maggots mate. 
There just like pheasants, always trying to kill themselves. 
Pigs are the way forward, and more return for your hard efforts (food wise). 
  
As for money, you wont make any on such a small scale, you will break even or better, but it will not be profitable. 
  
Profit wise, that strip of land looks ideal for a lure coursing event, pleanty of loons out there that would pay you money to let their pot lickers chase a rag about a field   . 
  
Just a joke, btw before anyone takes offence.
