I'm a freelancer. And, like other have said, the hardest part about freelancing is finding good clients to work with. Also, your value prop is at odds with the priorities of new freelancers.
When you first start out freelancing, you likely have no clients or only a few. You really don't need an assistant, automatic call scheduling, NDA generation. Also -- don't the clients provide the NDA's, not the freelancer?
With your existing product I think your target market is the experienced, established freelancer, not someone brand new to freelancing.
