ませんか
行いきませんか invites you to do something together. てくれませんか asks you to do something for me (手伝てつだってくれませんか).
ないかなあ
手伝てつだってくれませんか is put to the listener, and waits for an answer. 手伝てつだってくれないかなあ is addressed to nobody, and expects none.

Notes

くれる carries zero deference, so pointed at a superior or a customer the pattern presumes — てもらえませんか or ていただけませんか takes over.
Refusals answer the favor, not the grammar — ちょっと…, never いいえ、くれません.
