Dear [gender here].
Among my watchers - is there anyone, who might be familiar with game engines? Any - Unreal, Unity, others - matters not, only your skills level makes difference.
Of course, no need to be a master of intergalactic level - but not a "I once seen an icon of [engine name here]", please.
Asking with professional experience behind, not "we're just fooling around", don't worry. That means, that our team - small, but brave - is skilled each in their field - and you are exactly what we need at the very moment.
Go ahead and don't be shy, note me, please, if you are interested.
Um.... Not sure if this is any help, but... I can use unity. I mean, I suck at it. But. I can use it.
