Synonym for "for the time being"

I’m writing an email and I want to ask them (Career Development Office) if there are any volunteering opportunities for the time being.

But, the way I wrote it in the actual message doesn’t really match with saying "for the time being". I’m looking to say that in a more proper and formal way.

The meaning I want to go for is something along the lines of "temporarily" or "for this period" or "currently".

Are there any suggestions?

---

For the time being = a bit informal

Temporarily = sounds as if you are not serious enough and only looking to volunteer for an hour and then give up

Momentarily = ? sounds like you couldn’t come up with a better wording

For the moment = for just ONE MOMENT ???

seems like I cannot come up with the word to describe in a literal and formal, at the same time, way what I am looking for.

I want to say something along the lines of:
I am available now, and in the near future, but after that, not anymore.
