Bump for an interesting biz concept.
Some testimonials from well-known happy customers would enhance the appeal and lend additional credibility (not sure who the company is in the sole testimonial).
A less expensive starter (trial/try us) package with an upsell(s) to the full package, including some of the services that you mention you do not currently provide, could be helpful for your customers and additional revenue streams for you as well.
Good luck...
