Hello, we spoke about this project, you sent me a message and I was not online.
I did some numbers:
To get 100k votes in 10 days you need about 10000 votes by day
If you can do 5 votes by registration, then it will be 2000 registrations by day, which is a lot.
I think you should find more than 1 people for this, because even working 10 hours a day, no one can reach 2000 registrations and 10000 votes.
You will need 4-5 persons to do this (75-100k votes) for about 60 dollars each (if you find someone who work so many hours a days for less, great, but we sure they understand exactly how many hours will need to work on this, or they will not finish the job)
My offer is 500 registrations a day, which is 2000 votes by day, and 20000 votes at 10 days (your needs). The cost: $55. I will do this in baches (4 baches: $11 milestones for every 5000 votes).
working hours: (if you want to share this with another freelancer), it will take around a minute for every 5 votes at best. This is 400 minutes work a day to complete 2000 votes, and 66 hours work for the complete job (20000 votes). Which is like $0.83 by hour.
My advice is to share this information to any freelancer who take this project because if they don't think about they will fail you.
Good luck with your project!
