It is possible to turn a profit off your quail. At the very least, you can cover the cost of feed. This is true even with 30-40 sq/ft of yard space. Let's assume you have a 4ft x 2ft bachelor pad and a 8ft x 3ft hutch for breeders and 3+ week old hens. Put a colored zip tie on the ankles of your breeders to keep them sorted. Here's what you can reasonably expect on the low end: $5 a dozen for hatching eggs. $3 a dozen for eating eggs. $1 per day old chick. $4 per 3-4 week old female. $3 per 3-4 week old male. $20 for 3F-1M (8+ week) breeding set. $25 for 4 butchered whole birds. $5 for an adult male reptile feeder. "Eating" eggs went into the fridge, "hatching" eggs are weighed and stored at ~55F for up to 5 days. Feeders are frozen, feathers and all (or live maybe). Males are plentiful, so use those to butcher and sell. You could maybe get more in your area. I sell 20 eating eggs for $3 when my supply is high. Selling 4 butchered adults more than covers my costs to raise 50 birds (+20lbs of freezer meat).
