That's easy, participate in 20 discussion thread here, then make 20 comments in different blog post every day. That is about 40 links. However, Google may not index all the content or your comments may not get approval. It is safer to get a bit more if your target is 40 links per day.
I offer a service of 150 manual directory submission from PR 0-6 only $2. more info : http://forums.digitalpoint.com/showthread.php?t=1624975
Forum posting with dofollow signature links is a good way if you are just about quantity but I would go for qualtity to and then it will take longer ...
You can do it a couple diffrent ways I really like the free traffic system at www.freetrafficsystem.com and you can submit to directories at www.directorycritic.com. Both of these should easily give you 30+ backlinks daily.
What are you using to submit to 3k blogs a week? No way you can manually submit blog comments that way. it is software?
I have used freetrafficsystem before for some keyword research and I can say Dim. is awesome and extremely helpful. I cant see how you use it for backlinks though. I tried to submit an article using that tool on their website and nothing every happened. Is that directorycritic for real? you sure those links show up when you check?
forum posting, blog posting, tweeting and content refreshing are the best ways to get backlinks but dont do the excessively
write 1 article........ put it on EZA or AB.. then the same article with different titles and rewritten 1st paragraph to 10 article sites. = 11 5 blog comments = 16 20 forum posts = 26 social bookmarking articles = 50? 10 web directories / day = 60 gogogo of course, you need to randomize the shiz... not 10 daily.. but 5 6 7 13 6 4 0 1 18 etc
Use different strategies. Any scalable link building strategy may considered as spam tomorrow so dont depend on single one.
Well you can try blog commenting , forum posting and article writing , can get your 10 backlinks easily everyday though sometimes may crack your head off finding relevant blogs to comment.
When you are already writting new content go for article marketing like unique article wizard and free traffic system
