Best way to go from Chamonix to Geneva in winter

I am from Brazil and I will go with my husband and children to Chamonix in january/2018. We will stay some days in Paris and then we will go to Chamonix by Train. We´d like to try to ski.

Our flight back to Brazil takes off from Geneva in 15/jan/2018.

Please, what is the best way to go to Geneva, from Chamonix on winter ?

There is no bus available yet to reservation and the train is very expensive and take much time.

Are there bus on winter?

When is the time to buy and take reservation?

Some specific website or bus company?
