How fast can I get a divorce if my husband and I live in two different states?

The fastest you can get divorced in Colorado is 91 days after he is served with the petition for dissolution of marriage. The fact that he is in Georgia does not make a difference. However, to be finished in 91 days will require his cooperation. If he does not cooperate to get his financials filed and sign a separation agreement and couple other steps, it can drag on (generally no more than 6 months though in a case like yours). A lawyer can be helpful in cases like this by knowing the process and keeping the process moving forward to get you done as soon as possible.
