Career change advice - consulting

I am in need of some career/life advice.

I’ve been involved with a dozen SAP implementations (and counting) over the past 4 years but my company decided not to upgrade to a new system until 2017. It’s a better fit for us to improve our existing infrastructure in-house using our existing modules because we have the talent and ability available to do so cheaply.

I've been charged with a portion one particularly massive project (with huge impact) and it’s going fairly well so far. It has been a great learning opportunity for all of us, and we don’t know of any other company in the country that is attempting what we are doing right now. I’m learning things about ABAP language that looked completely alien to me two years ago along with configuration of our upstream supply chain and the business decisions that drive them.

The downside is that I am not going to be able to learn the latest and greatest SAP module in my area until at least 2017. Companies like ExxonMobil, Apple, General Motors, and even many mid sized firms are implementing this new module but we are not. I’ve been thinking about making the jump into consulting while I’m still young (it involves heavy travel).

I've recently found out that my wife has been accepted into medical school in Pennsylvania and, unless she hears back from the local school here soon, we are moving. We are currently without children and I’m still (relatively) young. I think there is no better time than now to seek out opportunities with significant travel that involve implementing this particular module (SAP TM suite), which is the area that interests me. Ideally, I can get onboard with a consulting company within the next 8 months, sell the house, and move to PA and travel from there.

When we start having kids, I won’t be able to travel anymore unless my in-laws follow us up to PA. I figure that I have a window to make a jump like this, and I want to exploit that to gain experience in one particular function module in SAP.

I’ve put my resume up on Dice, and monster on Monday and I’ve even applied to a few positions. I’ve made a few contacts via LinkedIn and have even gotten a few call backs – most from head hunters looking to find someone permanent to handle what I already have significant experience with (which I obviously can’t do unless it’s in PA).

I’ve cultivated a fairly narrow, but deep area of expertise here and I’m interested in something specific (full SAP TM implementation, preferably at a manufacturing or oil/gas company). What would be a good place to start looking for jobs like this without alerting my current employer to my potential career change? I don’t think it’s wise to contact consultants that I’ve met through work (even though SAP NA is actually based out of Philly). Where is a good place to look for positions in this narrow scope? I'm really not used marketing myself quite like this. Any advice would be appreciated.
