receiving and short-term storage in UB (Ulaanbaatar)

I'm with a volunteer health care organization called Nomadicare that works with nomadic herders. We're trying to get a product for distribution to herders made in China, then shipped to UB and stored in short-term storage until we can pick it up later in the year.

Does anyone have a suggestion for a company that could assist with customs receiving and short-term storage.

I already know about UB Trans Co and MoveOne. Any others?

Or is there a better solution for short-term storage than hiring one of these companies?

Thanks.
