Are you going to fabricate your own chasis for the device, or will you require a core?
I cant immagine there being much profit for yall making powersupplies. You most likely wont sell thousands of them, and if you did you would have to outsource the pcb production and probably the assembly, as you wouldnt have time to solder all thoes diodes and caps and other things.
Even if you did setup shop in your garage and made your own pcb's, what would you do with all thoes gallons and gallons of waste ferric chloride? You have to pay to dispose of it properly.
If i remember correctly i was able to find a chemical supply company who would sell me ferric chloride in 55 gallon capacity for around $250.00 a barrel. Turns out they use lots of it in wastewater treatment plants, look for their chemical suppliers if you want to obtain the stuff.
Another good place to get the stuff is companies who sell to engravers. It can be bought in 5gal capacities for a vastly inflated price. Occasionally on ebay people will sell kilogram packages of powered material.
Ebay is a great place to find stock copper clad board.
