If you're in finance I don't know of any specific agencies or companies you could contact, but this area is loaded with large manufacturing and services companies who might hire in that department. Harrisburg and Lancaster both have a lot of financial-services companies, bank headquarters, etc. York & Hanover are more blue-collar manufacturing. We have a lot of company headquarters in this area and large branches of large companies such as Johnson Controls, BAE, Harley Davidson, etc. We are also loaded with colleges, universities, and large medical centers in this area--throw a stone and you'll hit 3 or 4 universities. I assume these places would have positions in finance. Between Carlisle, Shippensburg, York, Lancaster, and Elizabethtown, I can count--without trying--10 colleges or universities. There are more.

Also, we are close enough to work in Maryland to take advantage of typically higher wages and live in PA, where the cost of housing is dramatically lower. Lots of people commute to Bel Air, Hunt Valley, ####, and Baltimore from southern and mid York County, and to eastern MD from the Lancaster area. Most of these places are a half-hour to 45 minutes from where one would live in PA.

Wage wise, about all I can say is that in some fields, the pay is far higher than for equivalent work in western NY (my husband makes about 1 1/3 times here what he would there). Most people we meet from NY tell similar stories.

Well, you need to make up your own mind, of course, but overall I'd say the COL here is lower and the employment outlook and wage scale higher than in Buffalo or Rochester. The salary calculators will tell you that wages are  higher in Rochester than here, but the higher cost of living way outweighs that difference. I just about hyperventilate in the grocery store every time I'm up in NY and have to go grocery shopping--the food prices are so much higher, I get sticker shock!

In reality, we have not found the wages to be higher in Rochester across the board. They are much higher in my husband's field here, but lower in my field. I have read that in certain parts of PA, there is a shortage of skilled labor. At my husband's firm, they have left positions unfilled for months because they cannot find enough exceptionally qualified people.

And, lastly, while housing in Buffalo may be cheaper than here, it's not by much. That wasn't true years ago when we moved. Housing prices here were about 10% higher than in western NY, but the prices in NY have started to catch up. I sell real estate part time, and try to keep up with what's going on in both markets. Some parts of the Buffalo area you can get really nice  homes really cheaply, but that's because there aren't any good jobs left in those areas. The chemical companies are gone, steel industry gone, etc. 

Whatever you do, best of luck to you!
