Creating ERC20 Token + Governor

Hi there!

I would like to launch an ERC20 token for my freelance marketplace. Let's say it's called 'MOXC'. The goal is to create a token with 25,000,000 tokens total. I also want to have a governance mechanism for proposals. Proposals will be for changes made to the site, additions to the protocol, and basically voting on how the site operates. I want to make it so users who own the MOXC ERC20 token can vote on the proposals.

What is the standard procedure for creating this? I discovered the TokenWizard and will most likely be using it to create the ERC20 token. Do I need to implement the Governor at the same time I launch the ERC20 (additional code needs to be added to the ERC20 contract?) or can I launch the ERC20 token AND THEN launch governor later on?

Thank you so much for the help, I am researching as much as possible right now.
