20-Year Prospect
The good news is that museums will always need someone like you to provide the 411 on objects discovered deep in the Saharan sands. The bad news is that the chances of you finding any additional objects out in those sands are diminishing thanks to looting, violence, and general mayhem.
Since President Mubarak got canned back in 2011, Egypt has gone through a few crises and this has allowed people to run roughshod over archaeological digs. Not even the artifacts housed in Egypt's museums are safe: in August 2013, many ancient objects at the Mallawi Museum in Minia were stolen (source).
This is where technology can do some good. Today's Egyptologists use satellite imagery to identify where looters are at work and how much damage they do to a site. Armed with information about the site's location and age, Egyptologists can then identify artifacts up for sale that may have been looted.
Egypt is a big place, and there are still really cool things out there in the dirt for you to find, which is why your career will exist a couple decades from now. Let's just hope you can still get a passport there if you need one.
