You should post your requirements and what you’re willing to pay in our Free Lancers section…

Hopefully, one of our freelancers will accept your proposal.
If you’ll looking for help to do it on your own, you at least need to attempt it and show us the code you have already and we can point you in the right direction.
No you do not want to do this, why on earth would you…?
What @JimL is saying is that you should never store a users password.
You can read more about that here.
