I'm currently pulling traffic to my website through google adwords in an effort to get them to sign up for a buyers guide (I'm tracking this conversion). I then have a sales team follow up with them. How do I track that conversion? Are there any online services? I'm trying to make my whole ad campaign more efficient and see exactly which keyword phrases are converting to sales.

What we recommend is pulling in the Google Analytics data into your CRM/form. It will include all Adwords data, and you can then run cost/revenue analysis from your CRM.
Alternatively, grab the gclid into a hidden form, and then do an upload into the new Google Adwords business center, of the GCLID, and the lead value. You can then run reports off of that data. See:
