Mr solubilty your absolutley right with what you say about the tax issue,if you matched your income with having staff therefore come off the tools you would be earning way over the VAT limit,unless your prices were to go up 17.5% your 25% profit would become 7.5%.Yes you wouldn`t be working but it would still be a headache organising the work and covering holidays and sick days,don`t forget the day to day running costs of the business ie vans equipment etc.Without it being properly thought through you could end up losing money from the start,when employing you must have money in the bank.
