Im not interested in the task but i just want to make some recommendations you could use an escrow for these job and especially with pur current reputation few people will only trust you.
Another one is you could increase your rates coz 500 is a bit to low and might take time to get confirmed and are you the dev of mrai coin?
500m rai is lowest pay. now paying considering daily price change. i only take 10%
There is also other member doing the same thing here, and he is ''Hero Member''
So why don't I work with him if just the same rate?
