Starcraft 2 legacy of the void beta account

I am interested in selling my main Bnet account as it just recently got the LOTV beta invite. This account has:

Diablo 3 with a level 60 char and another one with many legendaries

A level 90 wow char and an 85 one with over 20k gold on the account (I think)

A level 40 heroes of the storm account with alpha and beta portrait and almost all heroes unlocked.

It has starcraft 2 Wol and Hots with the LOTV beta

How much would this Bnet account be worth?
A/W 300$ from trusted members?
