Online Research into Alternative Investment & Carbon Credit Forums/Groups

I am looking for someone to research online for me, looking for communities of people actively discussing, engaged in and interested in alternative investments, high yield/return investments, and also groups of people interested in or discussing investments in carbon credits or the carbon market. They may be high net worth or sophisticated investors.

I am also looking for websites specialising in these types of investments and providing information about these types of investments.
This is a desktop, online research project that is not difficult.
They could be based in the UK, Europe, North America, SE Asia or Australasia.
I would expect hundreds of sites at least.
The main thing is that I am looking for (preferably) large groups of people to engage with on these topics, or people who have access to such groups through their sites, blogs, video channels etc.

I am looking for:
• Active Forums
• Regular Blogs/Bloggers
• Membership sites
• Newsletters with an audience >250
• Facebook Groups – members > 250
• LinkedIn Groups – members > 250
• Websites especially providing information or reviews about carbon investments and other alternative investments, or commentary about these markets, especially those sites aimed at individual investors.
• Etc.

Please provide results in excel spreadsheet with url/web address, group name if applicable, and number of members. I am not interested in groups with less than 250 members.
I expect this work to take no more than a week.
I pay 100% on final delivery to my satisfaction.
I would ask for a checkpoint halfway through our agreed term.
