Spanish Speaking Girls!

I'm writing our TY cards and I wanted to write my grandparents card in Spanish. Can someone tell me if the below translation makes sense?
Thanks!!!


Thank you so much for helping with our wedding. We could not have not done it without you. We love you very much!

Muchas gracias por ayudarnos con nuestra boda. No hemos podido no lo han hecho sin ti. Te queremos mucho!

Is this for both of ur grandparents? If yes, u can say it like this:

Muchas gracias por habernos ayudado con nuestra boda. No hubieramos podido hacerlo sin ustedes. Los queremos mucho!

Yes- Thank you!!!
