Continuing the discussion from Hidden service set up:
As Whonix gains in popularity and complexity (which Qubes arguably contributes to), you may be faced with increased requests.
- Although we all trust you implicitly by using Whonix, code can be audited, your actions via remote-login much harder (or much less interest for 3rd parties to do so anyway).
- Setting up VNC is no picnic. You'll spend half of your time getting VNC operational.
How about: Helpee proposes certain amount for payment. Then you write a custom guide tailored to their virtualizer, Whonix version, hardware, etc with step-by-step screenshots and if needed, support via IM or VOIP. Side benefit of this is that there is now a detailed walkthrough that can be added to wiki (with any identifying information redacted of course).
If you choose to decline a proposal, then Helpee posts proposal to Paid Support forum where anyone can bid on the project. If a deal is reached, a 3rd party site can provide escrow, such as xbtfreelancer.com or bountysource even. In exchange for payment, tutorial is written and posted to whonix.org where it can be audited.
