Ask HN: Any services to help manage freelancing process?

I am working on a startup idea, to help freelancers be “more professional”. A saas platform which streamlines and create a process for freelancers, making clearly defined process from collecting client details, client-NDA, requirement collection, proposal, managing the process, delivery and payments.

Say I create a personal website for you with a "start project with me" flow for your clients which will get their details, sign NDA, a form to collect requirements that end with a call scheduling(calender stuffs) to discuss the project. This will help you all the initial stuffs clear before talking to them and you don’t have to do anything. Would you be interested in paying $10/month for such a service?
