What SaaS should I use to coordinate email communication with customers so our whole marketing team has one consistent voice?

Do you have any internal sales professionals? You should at LEAST have an internal sales director who sets the strategy for a sales force. Then you determine if the proper path is a contracted sales force. I've known companies that have used outside sales teams however NONE that have seen the type of success that outweighs having an internal team.

It sounds like you're off to a good start with your lead generation. While it is important to keep lead volume strong, it's even more important to have a way to follow up with these leads and continue pushing them through your sales funnel until you can convert them into revenue. Without that follow-up, especially if you're generating leads through PPC, you're likely wasting the budget and energy you're putting toward your marketing efforts in the first place. The first thing I'd recommend you do is create an automatic "kick-back" email that triggers as soon as a lead downloads your ebook. Be sure to thank them for downloading, give them a link to access the ebook, and then (most importantly) include your call-to-action for the next step you want them to take. Second, figure out how you're going to handle these leads from a sales perspective. If you're stretched for bandwidth, I'd recommend a system where you assign dollar values to different types of leads, and only have a sales rep follow up with your highest value leads. How much is an ebook lead worth to your business? How much is a demo lead? What about someone who actively requests to be contacted? You'll find that as you get these systems and processes underway, it'll be extremely useful to have a CRM system both for integrating with your marketing efforts and for helping your sales team to be able to sort and prioritize the leads they're reaching out to. Lead conversion is a daily focus of mine in my role at HubSpot, and I'd be happy to chat further about how to get a strong marketing/sales funnel set up so you're better equipped to manage the leads you generate and better able to convert them into dollars. Let me know if there's anything I can do to help!

If you have an enforceable contract, the client is obligated to pay for the services received. As a business owner, I would be very concerned if a SAAS was demanding upfront payment for 2 years.

This is not my specialty, however, I have been in your position many many times -- maybe this will help. If the product is in-tangible, then look for JV partners on the Internet. Try to find an expert that deals with these JV opportunities (like me). If the product is physical, then look for sales organizations that have networks of sales people across the country. You do the deal with the organization and the independent network of sales people sells your product. It's a sweet setup if you can negotiate a margin that works for everyone.

Personally, I'm a fan of sales comp plans being tied to ongoing performance. Sure, the salesperson should get some of that long tail, but only while he continues to work productively at the company. Once he leaves, he should lose the tail, since someone else will likely need to step into the relationship with his customers. But there are too many variables to give a universal answer. The true answer is this: You need to pay your salespeople enough so that they are motivated to keep working for you rather than seeking alternative employment. This means you need to analyze at-quota pay, and ensure that your base and commission structures provide a market-level of compensation at quota. You can muck with anything you want as long as that goal is met.
