We are hopefully about to lower the proposal cost from ~$500 to ~$100. If you want your proposal translated, hire a translator.
No, no, no. Re-think what you're saying here. Dash is Digital Cash, that means it absolutely must be inclusive and incentivise people globally. If it doesn't, then you automatically exclude more than a billion Chinese speaking people, they'll end up doing their own thing in their own language, and maybe they would be inclusive where dash isn't. Dash is also meant to be "easy to use", therefore not tackling language barriers would be a serious and costly mistake.
I'm not suggesting we cover every language, but there are probably five or six languages that can't be excluded. Of the top of my head I would say, Mandarin, English, Spanish, Russian, French, and Arabic.
The submitter would also feel they are at least getting something for their hard earned money, instead of the dash getting wastefully burned. Let's not forget, dash is very much in the service industry. Good customer facing support, not just to end-users but a pain-free experience for submitters too.
