[R] glm - poisson

I have a question on glm - poisson. I would like to fit a model on proportion of counts with some factors, and I decided to use glm - poisson because count data is essentially related to poisson. However, since I need to deal with proportion, and glm - poisson does not allow non-integer responses, I am thinking of adding an offset term = log(total). Is it the right approach to it? or should I use quasi-poisson family, or should I even use weights?

Thanks for your help!
