Please help with auction draft

[9er Fan]

I've never done an auction draft before, and could use some help. Can someone post a link to amounts paid for players in a draft this year? Also, any tips from auction draft veterans would be appreciated. Are there any "rules of thumb" like spend X% of your budget on your top 3 players?

Roster is: 1QB, 1RB, 2WR, 2Flex, 1K, 1D, 7 bench spots. The number of bench spots is reduced as the year progresses from 7 to 2.

Our budget is $1500.

Thanks in advance.
