If you have registered with right Search Engines you may need no further supports from other agents, if you have already a registered domain. This is what I think.
Can they give you a sample of the links? Are they on nonsense pages? Are the pages cached by Google?
What happens after the 3 months? Are the links taken down? Do you have to keep on paying for the links?
These are the questions that I would ask.
My opinion would be to react badly to this offer. Selling a certain number of links in a timeframe means they're focused on volume not quality. And that means the links are likely coming from some sort of farm or network.
Without a lot of very rigourous questions and clearly defined parameters as to where the links are coming from, age of site, placement on page, topic of page and site, and so on, what you're getting is a load of low quality links. That may give you a temporary boost, but could maybe hurt your rankings in the longer term.
If you're going to buy your links,buy them one at a time.

I agree with Wheel, but would take it a step further than any directory that's selling placements won't help you. Google is insane about finding paid links and punishing people for buying them to increase rankings.
In fact, I would try to avoid even the sites that have free placements, but offer you "improved" placement for $$$. Google can't necessarily tell which are paid and which are free, and won't easily find the free ones anyway - so the directory is probably completely useless for link building.
I have read multiple places that is you have a link to your site that you will NEVER be penalized. Only not given credit. Why would they give you negative points for something that possibly isn't in your control. What would stop a company from setting up a system to lower a competitors links. Nothing, I think they know this and because of this give people nothing for bad links instead of giving them negative points.
This is generally not a great idea on numerous fronts:
1. Generally automated, meaning the websites you are getting links from are part of a predefined network or group, who often openly link between each other and to many other websites, lowering the value of the link you get.
2. Less control on link build rate
3. Less control over the actual sites that link over to you.
