I'm also in PA, we're not too far, we come to bethlehem to ice skating competitions.
Anyway, here's what I have observed since becoming a lactation consultant.
Around here the hospitals make you have your RN to be hired as a IBCLC. There is a job market for hospital LC's and they make about the same amount as the nurses. The same holds true for doctor offices that hire LC's, they seem to want them to have their RN.
As a private LC, I can't say I think there's a big business. Most of my clientele are from my midwifery clients or word of mouth from my clients. I only get a handful of paid clients from the general public.
I attended the private practice LC conference a few years ago, it was great. But almost all LC's do other kinds of work, such as doula, CBE, work another job, etc.
I think that if insurance companies paid for LC's then there would be a much greater demand, but I find that people aren't willing to pay. And I am pretty cheap, much cheaper than the other LC's.
There might be other jobs out there, like at WIC, and probably some other places.
Not to be pessimistic, but I want to just share my information, it's a great job and I love it, but I certainly couldn't do it full time unless I went to work for the hospital.
