Googling suggests 初めてお目にかかり、光栄です

Jisho backs me up on this, but I don’t really know how common it is. If nothing else, it’s a fair bit more formal than Kyle’s… uh, I mean, thisiskyle’s suggestion.

Are you talking to yourself again, Kyle? =P

I take it these are people you work with (forgive me for doing a bit of stalking to get some perspective), so you will probably want to say something fairly formal (my earlier suggestion is probably not appropriate). I would hesitate to say anything that you just looked up online, not necessarily because it’s likely to be wrong, but, even if it’s not, I’d advise against saying anything that your not confident you’ve internalized (unless it’s some sort of set phrase). If your ability is at level X, you should aim to listen and read at X+, and speak and write at X-, at least outside of a learning environment.

Have you been communicating in Japanese up to this point, or in English? If it’s been English, I would stick with English, other than perhaps a yoroshiku here and there. If you’ve been discussing engineering in Japanese, you are probably one of the more advanced people here…

With that said,here’s another possibility – 直接にあって嬉しいですよ。
