[Grammar] How to ask for help politely?

[ira_www]

What is the correct way of asking politely for help?

1. It would be nice, if you could help.
2. It would be nice, if you can help.
3. It will be nice, if you help.

Thank you,
Ira

Delete the commas and they are fine, though #3 is not collquial.

There are many other ways:

Can you help me, please?
Could I please ask for your help?

Could you possibly help me?
