I can not provide you a software, but i can provide you vote after a regular time interval.
Just PM me details, willing to start right away.
We are team of nine members. We can provide unlimited number of votes for any online contest in really short time for our client. But, if you have enough time, then we will vote slowly. So the number of vote will increase gradually and vote will not look suspicious. Or 4k vote in 24hrs if need fast.
Let us know time and budget for your work. Just check our work.
Thank you
