WTB Account with Rock Band 1, Rock Band 2, Lego RB and RB Blitz Export

Foolishly, I never exported the older Rock Bands and now I am SoL on importing the songs into Rock Band 4.

I am looking for an account that has paid for the Rock Band 1 and Rock Band 2 exports at the very least. Lego and Blitz would be a bonus. DLC is not as important but of course I will take into consideration.
