Really need trade advice - No WR depth

I’ve never successfully completed a trade after 3 years of playing. Please help me figure out a way to make some trades to strengthen my WR core. It’s a 0.5PPR league and here is my roster:

QB: Kirk Cousins
RB: Leonard Fournette, TJ Yeldon, Alex Collins, James Conner, Carlos Hyde, Kerryon Johnson
WR: Odell Beckham Jr, Adam Thielen, Nelson Agholor, Chris Hogan, Christian Kirk
TE: Trey Burton
DST: Chicago Bears
K: Dan Bailey
