Forum Signature Link Building

I need an experienced forum signature link building specialist. Task is very simple. Register with various forums and make posts like every user does. - All forums must be dofollow, well indexed and with homepage PR of atleast 3. - You have to find forum list according to niche. - All forums must be RELEVANT. Currently we need health forums only. - All links must be search engines visible. (I.e. Some forums shows links only after login. We don't need such forums.) - No Spam. You can do this genuinely. - Maximum 40 posts per forums where you must start 2-3 threads. - No posts on threads with hundreds of reply. (i.e. If you post on thread where reply goes on 4th page of that thread, it won't be accepted.) - You must know forum link building strategies. - Reports should be submitted in XLS sheet on daily basis. If you already did this before, provide me samples, list etc to get accepted easily. If you passed any exam here with good results, that'll imporve chance of being approved. This is for long term partnership. Current bid is for 500 forum posts.
