@disciple777 I know someone who is offering a DaaS and is having good success. This model works well for bigger companies, not the little ants you are debating with here. Larger business is not going to go rooting around Upwork to find good designers.
Using a DaaS makes sense for these businesses because the subscription business model lets a department avoid having to go through a lengthy vendor procurement process or get into a conflict with a centralized design team that reports into corporate marketing etc.
also, they often need a team: project manager, art director, video...not just a couple of designers. Having access to a vetted team that has worked together for a while is an attractive proposition.
I have used Upwork for years and while there are good resources to be had for cheap, you have to kiss a lot of toads to find your prince or princess. Many scammers on there know how to game the system. Anyone working in a big company doesn't have the time to deal with all the flim flam to save a few bucks.
