Looking ideas website signups make money

Hello

I am looking for some ideas for making money from website registrations.
First I need good affiliate program.

I have idea for Luxecash install combined with another install affiliate(not approved yet with either)

Basic idea is people sign up to website and during registration they are asked to install something to help with website downloads.
This takes care of Luxecash(if when approved) and the other binded affiliate program.

But is there anything else I cn attach during registration to maxmize from signups?

I may also need someone to do this so if anyone here can do it please reply here with your guesstimate.
Thanks
