Does anyone have experience working with a third party who helps select Offsets and/or RECs that conform to the ACUPCC Guidelines?

We are considering a sizable purchase of both RECs and Offsets, the former to match our consumption of electricity and the latter for our remaining emissions, most of which come from travel and commuting.

I have read the ACUPCC Carbon Offsets Guidelines and I am fairly familair with the broad issues involved in selecting high quality RECs and Offsets. But even so, the prospect of selecting the best offsets, in particular, is still extraordinarily complex.

Thanks in advance for any suggestions.
