Its no more a minefield than working for yourself, you employ them, pay them an hourly rate minus a percentage to allow for holiday pay, change your insurance to allow for employees, the only real difference in tax will be employer NI and the workplace pension which aren't hard to work out and allow for, if your plan is to grow beyond the VAT threshold and your mainly domestic then also make plans for it now.
In my opinion good reliable employees need to be paid well so if you expect massive returns on employee labour you may be in for a shock.
