How Would You Contact These 14,000 leads?

Hi all,

Wanted to get some ideas from the forum about how to attack a list of leads that my company has come into.

My team and I offer conversion rate optimization for PPC campaigns, as well as some local SEO, web design, and social media management.

I spent a VERY heavy investment with a data analysis company here in Canada to get a list of small-medium sized businesses who are currently spending on digital marketing.

The list has finally been created and I've got 14,000 leads with the following information:

• Company Name
• Company Phone Number
• Company Mailing Address
• Decisionmaker name
• Decisionmaker email address
• Estimated Adwords PPC Spend*
• Estimated SEO Spend (including relevant keyword positions in Google)**
• Estimated Yellow Pages Spend***
• Facebook Ads: Yes/No****

In Italics, you can read a quick summary on how this data was quantified if you're interested. If not, skip below the italics...

************************************************** ************************************************** ***********
*Estimated PPC Spend was based on keyword planner data, and other factors and is presented within ranges of $500.
**Estimated SEO Spend was based on keywords tracked in organic results, the difficulty to rank those keywords based on 1st page competition, and prices were determined based on the pricing that we would charge to rank those keywords.
***Estimated YP spend was based on placement in online and print directories, in Canada, YP prices aren't too hard to find so I expect these numbers to be reasonably accurate.
****We don't know information about how much the prospect could be spending in FB, but at the time of the report, they did have ads running.

My cold-callers and I have dialed a random sample of 300 businesses under the pretense of a survey, and we've found that out of the 110 businesses who agreed to participate in the survey, the information we had about them was correct for over 85% of these 110 businesses.
So we know our list is good quality.

I've never had a list to contact that was this detailed, and I have no doubt that my team and I can make a good ROI from our investment in having the list created.

Here's my question:

We're trying to come up with the best way to initiate contact with these businesses, and there are so many scenarios that it's becoming overwhelming. We have 2-3 strategies that we are considering in how to make the best use of this list, but would love some suggestions from the Offline Warriors about how THEY would make contact with this list.

Here's our goal; book a 15min sales presentation over the phone (and then obviously structure follow-ups to get the sale)

How would you contact this list?
