That's a tough one... And i don't feel comfy about it on my own. Please help.
1) Recently we've been working on a identity for a hydrologist. We picked "Purista" as a leading typeface. It was ment mostly for stationery and hydrologic reports – both headlines and body text and we're happy with it's tech look. Unfortunately, we encountered a serious issue with mathematical symbos and greek, wich Purista does not support.
2) As the logo is much in sync with purista, we should stick with that one (a very close inexpensive match with support for what we need would be as perfect as is non-existent)
3) There's no budget for any high-end, multi purpose killer bundles.
