Not sure I agree with the premise that the real bottleneck to profit and getting enough drone work is the workflow process.
It is clearly a lack of sufficient paying customers who are willing to pay for drone services at a price that is profitable. That's a marketing problem where the supply is almost infinite and the demand is fixed.
It has been a race to the bottom on pricing, while the bar to entry among competitors has been reduced to almost zero, as many amateur pilots now require a 107 certificate even for most of their recreational flights, and already own the necessary equipment to compete, with better pilot skills than most professionals.
In most fields needing regular drone work, either the previous buyer has bought their own drone, and is now doing the work themselves (like real estate agents), or larger companies (needing inspections and photogrammetry just buy drones for their own employees to use, instead of outsourcing all but the most complex of drone assignments to an independent drone pilot.
There is still profitable drone work out there, but the real problem isn't the workflow. It's the lack of enough such paying clients for all the prospective independent drone work pilots to make a profit!
