Something like this has been a business idea I've been sitting on, but it's hard to get started (chicken egg, have to get enough customers AND tradespeople for it to be worth either's time), and could be capital intensive.
I figured it's actually easier to sell this service, at least to start with, to small and medium sized businesses which don't need fulltime staff for some trades oriented work, but have enough of that kind of work for it to be worth setting up a business relationship. But of course the issue with this is it's just a small business idea - you'd need to figure out how to add value to differentiate yourself from the thousands of contractors already doing this if you want to scale beyond the lifestyle level.
