Hi Chris
I've seen plenty of Indigo gi's before; actually, my sambo kurtka is pretty much indigo, as is my comp. judo g (or it was, once). It's quite a snazzy look, and I sometimes wondered about getting 'The Fighting Smurf' emblazoned tastefully across the back
I'm aware of a several suppliers here in Oz (hopefully they ship o/s). Do any of the following meet your specifications?

Both def. have indigo gi's (youtube 'jandejong' to see the actual colour, for example)

(not so sure about these guys...but the merchandize is cheap. Caveat Emptor)
Closer to you, perhaps something like this?
Which is 'indigo dye' according to sources. US Sambo sells great kurtka of this (and slightly darker) colour. Contact Stephen Koepfer at US Sambo Association
HTH
Addendum: try looking at the popular BJJ gi manufactors, like Koral, Gameness, Howard Combat Kimono etc. They have Gi's in every colour of the rainbow. Budovideos - IIRC - sells lots of diff. types of these gi's - and they sell pants separately (again, IIRC)
