Need to value a business - recommend an accountant?

[type-r]

I am looking to purchase a business and need a valuation based on a discounted cashflow or similar method. Need an accountant to not only take a look at the accounts over the last few years but also forecast future revenue and profit - especially given that this business has a relatively young workforce and profit will be affected given government plans for the national minimum wage is set to rise from £6.50 to £7.20 an hour from April, with the figure rising to £9 by 2020 for over-25s.

Can anyone recommend somebody, perhaps someone who specialises particularly in the purchasing of businesses? Turnover is less than 500k if that makes a difference.
