Hi,
I noticed you are looking for an environment / infrastructure / sustainability blog writer.
I am new to freelancer but very experienced in writing about this field.
As you can see in my profile I'm a published academic writer, and my day job is researching, writing and teaching in this field. For example I've recently worked and published on power systems, gas infrastructure, ecosystem services, green infrastructure and how these relate to things like quality of life in cities, poverty, climate change and urban economy.
I have bid at the upper end of your budget as I really think this is a good fit and that the quality of the work could be very high indeed if we communicate effectively about content and style.
I look forward to hearing from you and please do ask if you've any questions.
Very best wishes, Doug
