Smart contracts. Opportunity to vote on Waves Platform

Good evening!
We would like to as you about smart contracts.
We are members of the local public self-government (ТОС) in Russia. This organization deals with landscaping of the certain territory. We want to use the potential of smart contracts on your platform. First of all we need the ability to vote inside of our contracts.
What do we need to do this? Thanking in advance.
