That's cool man, give it a go. Let us know if we can help.
FYI, from your list we have already contacted:
Binance, Bittrex, Yobit, Cryptopia
+ some others.
Great. I've just created and paid Yobit Premium "Add coin" request. If everything goes ok BBP should be listed there in 4-7 days. Yobit is not a perfect exchange but it is well established with decent volume (40x c-cex volume) and it (more or less) works 365 days a year. I've put contact [at] biblepay.org as a contact mail so BBP devs should cooperate with yobit if needed.
