If a team (human) is committing to do the entire job by maintaining the required quality than i think u should not bothered much about the time frame. What you should bother most is the quality of the work without which entire work will not add the required value.

Further to have professional view, preferring to visit below sources..

It looks like a sure fire way to get your website penalised by Google, perhaps even banned - especially that bit about 2,500 directory submissions.

RSS feeding for blog posts is also iffy because it generates duplicate content and you can end up with another site ranking higher than yours with you blog post on it.

Spend one month and get 4 really high quality links - they will be worth far more than the hundreds your SEO team is proposing.

It won't work.

Their time span is not correct.

It may take minimum of 3 months

This can be done within one day or within one year but it is safe to distribute among one month.
