I think tools such as Termsfeed, Snapterms, etc. can be great, especially for general website Ts and Cs. HOWEVER, if you have a true SaaS business, then your TOS take on greater importance, as they define the relationship, liabilities, and obligations between you and your Customers.
If your site is reasonably comparable in offering to a competitor, then I think it is fair to look at what they have in their terms as a guide, but the more unique your offering, and the if you deal with anything regarding health or financial data, then it is one of the few instances where I would encourage you to contact an attorney, and one who is familiar both with TOS, AND with your industry. It should not cost more than $1-2K *max* for a TOS imho, and more likely should be a few hundred $ unless you have something truly unique to address.
Upcounsel might be just fine as their network is large, but definitely make sure you find someone with the right experience, as that will save you $ in the end (even if their hourly rate seems high at first) as well as net you a better TOS. There are a number of good startup attorneys in Seattle. Good luck!
