Trade help please! Playoff load up!

Trying to load up for playoffs , currently 7-1 in .5 ppr.

How can I land Ertz? Opponent is 2-6 and Ertz is on a bye.

I was thinking of offering Burton and someone from the following:

Ingram, Richard, Hyde, Royce Freeman

My locked RB are Gordon, mixon and Michel

What do you guys think?
