a) Can you make their logo smaller such that your biggest sponsor is still more visible and still seen as the biggest sponsor?
b) Maybe put the blue logo (or big sponsor logo) on your sleeve for distinction
c) stick with the blue... Unless its going to cost you a rediculous amount more, you don't want to reject money (especially if they're such a seemingly large contributor) because of something like team branding (that being said, I tottally get that its important... My team is branded up the wazoo, but you gotta do what you gotta do. Some teams would kill for that money- so don't be picky).
