the job center is very helpful and a free service.I get all my staff through the job center.Have had some no starters etc but to be expected.All in all a good way to find staff.The staff that I have now are all recruited through job center

The best thing is that it's free advice and adverts and probs the most recognized place for people wanting a job especially for something like cleaning to go and look.
Well done with your 70k contract

I started commercial work in much the same way, got offered some big contracts, too much for myself to handle and just learned on job.Be sure to get all the info regarding staff break entitlements, minimum wage and holiday entitlement and you will have to register for paye with tax office.Goodluck x
