To avoid wasting time and opportunity on each participant. I would like to spend some time observing the way the bounty team works in carrying out their responsibilities. At least a few days. Then, I can consider a decision. If you stumble in the first week, you will reach the requirement later. Just do your job in a responsible manner.
Its good to have a company that is easy to contact with however there project must be tested too. If they have records of scam if the team studies their project too. Find time your comfortable with to join and able to do task properly.
