I think that my current campaign is a great campaign, it's hugely popular and run by one of the most well known accounts on this forum. The campaign has been run efficiently and the project is based on an already existing company which have billions of dollars in government contracts already secured.
how long it take? WPP is almost running bounty for 6 mounth or maybe more.
How much you are planning to get?
WPP is not a good bounty for me. Also there is not much good bounty campaigns.
Try to find weekly paid ones specially btc payment.
