Any advice and/or feedback on experience with natural SEO firms?

Douglas P asked:


I am currently evaluating services for professional SEO firms with a
focus on natural SEO for several niche websites.

I have been in contact with domestic and international companies/
individual specialists, mostly through elance.com. Prices have ranged
widely.

Is there anyone out there who has had experience(s) with SEO firms
(bad, good, anything)? Any advice when looking to hire an SEO firm,
qualifications etc and measuring ROI?

Anyone with experience with offshore SEO companies (I have been in
touch with a couple in India and Romania), especially related to
lanuguage/content creation?

Any firms/individual specialists reccommended? Anyone in NY who could
advise me on this more specifically?

Thank you in advance for any help you can provide in this area!

Cheers,

d
