FYI, it's recommended that Beardie females be a minimum of 18 months old before breeding. If you breed them too early, calcium which should be going towards their bones goes towards the development of eggs, which can cause an early onset of MBD.
I would recommend looking up brumation (sort of like a pre-mating hibernation), as well as vitamin and calcium +D3 vitamin supplements, especially for your female. Make sure they both have proper lighting and heat, and that they get fresh veggies, gut-loaded prey, etc. For all the time other than when you specifically put them together to mate, each Beardie should have his/her own cage (40 gallon minimum. Wide/deep tanks are better than tall ones).
When the time comes, you'll need a large dig box for your female filled with dirt (I used a soil/peat moss topsoil mix with no added fertilizers from Home Depot). Some people use various mixes of dirt, pearlite, vermiculite, sand, etc. Just make sure that it clumps nicely and is nice and warm. (It's fantastic that you already have incubators, but I'll add info about them for everyone else reading this thread, so they get a complete breakdown of costs). You'll want to pre-order an incubator, and set it up a couple of days before the eggs are due to be laid to make sure that the temperatures stop fluctuating and are set between 84 and 86 degrees F. The Hova Bator is a great incubator for beginners. It's small and cost-effective, and can easily incubate 25 Beardie eggs held in plastic sandwich containers:

Hatchling Beardies need to eat 3x/day, and should be eating ~15 crickets/day. You can order pinhead crickets online at
http://www.wormman.com/pd_1000.cfm , or any other number of insect breeding websites.
Make sure the babies get plenty to eat! If they aren't given enough food, they'll start to nip at eachother's toes and tails. They should also be housed at no more than 5/tank, or less than that for the beginner breeder so you can be more aware of dominance issues. Also, make sure to house hatchlings on newspaper. It's not the prettiest substrate, but crucial to keep the babies from swallowing substrate and dying from intestinal compaction. Here's a website with info on raising hatchling Beardies:

As for $$, here's an approximate break-down of costs for 1 average-sized clutch (20 eggs) Btw, this doesn't include the cost of vet visits, vitamin supplements for the parents, etc. Just costs for the dig-box, eggs, and hatchlings:
Incubator:
$40
Dirt/pearlite mix:
$10
Dig-box:
$5
Sandwich containers for eggs:
$5
Boxes to house babies (5 beardies/box, $10/box):
$40
Lighting for babies (1 set of lights/box (1 day light + 1 night light) + clamps for lights (10 total) + 1 long UV bulb + stand which will suffice for all boxes):
$155
Crickets for hatchlings (20 hatchlings, 20 crickets/hatchling/day, $0.03/cricket, 1 month of feeding):
$360
Mealworms for hatchlings (20 hatchlings, 1 mealworms/hatchling/day, $.03/mealworm, 1 month of feeding):
$18
Veggies for hatchlings (1 bunch kale/week + etc. veggies):
$15
TOTAL COST (20 well-fed, warm, hatchlings, raised to 1 month old): $648
If you sell each Beardie for $50/piece, you will make $1,000 from the sale, which is reduced to $352 after subtraction of costs of raising the babies. This ends up being a $35% profit. However, remember that you might not sell all of your babies in a month, and simply feeding all those hungry mouths for 2 months instead of 1 will cause you to operate at a loss. Also, your female could become egg-bound which will cost $$ at the vet's office, you may decide to adopt out some of your babies at no cost if you're sure that they'll be going to good homes. If you decide to ship your babies, shipping in temperature extremes is not recommended, so you may need to either keep the babies for a while until temperatures are more conducive to shipping live animals or pack them in cold/hot packs and plenty of insulation. All of this costs money.
In total, raising baby Beardies is an incredible and rewarding experience, but should not be done for profit unless you're a large-scale operation who is breeding for a particular phenotype, where you'd be able to charge lots more for the babies.
Good luck with your beardies, and welcome to the BD forum.
