Hi,
An experienced forum/blog poster here at your service :)
I've done quite a number of projects that involved link building and/or just simple relevant forum posting, and I feel I am the best for the job. Two questions, though: do these 5 comments in total include sneaking in a hyperlink and does the forum allow posting links to new users? Also, would you be providing the 50-word comments or is that up to us?
I use VPN, so the US IP address doesn't pose a problem.
I charge $6 per post if it involves posting a link to a website that has a no-link policy :) Otherwise, if it's a website that needs a plain, relevant comment - it can be done in less than an hour, as you said, so I'm quite okay with... whatever you have in mind ;)
Should you have any questions about me or my work, I will be happy to answer. In the meantime...
... Have a great day!
Isidora
