I don't think anyone will need a guide for that rofl, as long as they play games they will earn IP. It's not like they have to do other specific thing to unlock the champions.
And I don't think anyone would help you with that, I mean come on. You're begging for referrals atm. Time is precious and time is money, they could refer themselves instead.
However, if you're dying for referrals you can purchase a service from trusted people for a low price. I believe it's like 250 referrals for $20 or $40, can't really remember.
