Job ID: 33251474

Budget: $30 – $250 USD

Document (NDA) has already been prepared, and I need to know which boilerplate template(s) used.. Standard template, since certain phrases are easy to find doing a simple search. But I need to know which one was used, so far checked Rocket Lawyer, Nolo, Legalzoom.
Keep me posted on sources that you have checked that are NOT the source
Need someone to research this, who has access to legal form databases
This gig will most likely have 3 milestones, one is to finalize NDA/noncompete/confidentiality agreement.
