Boxer's signing bonus?

[No-mas-tias]

I was researching and I read Ricardo Williams got a 1.4 mill signing bonus.

I was like WTF, how could he get that kind of money? Victor Ortiz got a 110,000 from Golden Boy and Pacquiao was going to get 500,000 from Golden Boy before the deal was declared not valid.

I know it all depends on amateur career and stuff but what's the normal signing bonus for a boxer turning pro?

Nothing unless you have Olympic experience or if the promoters think your special,i was offered nothing and i have a Golden Gloves under my belt.
