Forum/advertising research

Hi there, I need someone to do some research on finding 50 websites: (1) Find 20 forums: - That have a forum on management - The pages shall have a authority score of at least 40. Use: [login to view URL] - The forums have at least 1000 users and - at least 50 posts per months - It is possible to post in there with links to my own web page (2) Find another 20 advertisement options with management categories that are popular, e.g - large classifieds - local pages - interest groups (3) Find 10 Social media pages that allow posting ads that specialise on management I will award this within the next 4 hours. And it is to be completed within 24h I expect it will not cost more than $50. Thank you
