A Request
Request, Wish, Please
The noun form of request (don't be tricked by the い on the end, it's not an adjective). So, request goes to a request.
おねがい
The reading is the same like お願いします. Hopefully you're able to read that by now so you're able to read this too.
お願い！手伝って！
Please! Help me!
「ちょっとお願いがあるんだけど……。」「もちろん。言ってみて。」
"Can you do me a favor...?" "Of course. Name it."
中小企業は小回りが利くから、こういう仕事をお願いしても平気だろう。
Smaller companies take on new challenges more rapidly, so they probably won't mind if we request a job like this.
