Laugh all you want, but you're obviously the only one who didn't see, intended or not, how it came across.
But the suggestion of using the forum was actually a good one and not one to turn your nose up at. We regularly get big contractors on here advertising available work. In the absence of any single go-to place, its at least a starting point. Although there are a hundred or so members that have regular input, there are thousands of members who sign in just to observe threads looking for opportunities.
Tilers: find tiling jobs listed here - https://www.tilersforums.com/forums/tiling-jobs/
List the jobs you have, areas they are in and total meterage (no rates of pay in the open forum), and people should start sending you PM's with interest for more details.
You can ask for their experience, references and view their portfolio's of work, but as has already been said, vetting will be very difficult until you can make time to babysit a few people and see them start fixing anything. You can then get back on the tools or start employing more when the previous can be trusted to work off their own backs.
Also, fair play to you for getting the work in, but it would also help not to bite off more than you can chew. As nice as it is to have offers of work coming in, ask yourself if it's achievable with the manpower you already have before accepting.
Good luck.
