ANSWER THIS IN THE COVER LETTER:
Give me one example of Portuguese website/forum where you would place a comment, post, etc. with the link. More info below -> I will hire you if you will have good tip (and price)!!!
The goal is placing few comments, posts and new topics in public forums and web-portals and placing back-links to my website. Important is to search for "living" discusions and forum/portals which have "MOZ Domain authority" bigger than 25. And of course are in Portuguese.
(do NOT offer me any robotic link building services, link-farms, etc...)
You have to deliver 5-7 links (comment, post, etc.. with backlink!) to various forums/portals (which should take you 3-5 hours).
If I hire you and will like your work (back-links will be valuable) I will rehire you again and offer you few more tasks.
