I looked at similar some months back.
http://precisionmicro.com/6/processes/photo-etching-|-photo-chemical-etching-|-chemical-milling-|-metal-etching These guys wanted £1000 to get started. Still not sure how many discs I would get for that. And an american crowd; http://www.spgveco.com/precision+metal/products/precision+metal+parts quoted; 10 $66.65/ea 100 $6.65/ea 500 $4.65/ea 1000 $2.80/ea And a time tooling charge of $665.00 So, all in all, unless you're pretty serious about it, it'll cost a bit. But I'd be curious to see what pricing you get. I tried hard to source 'stock' discs, but they would have none of it.
