It is well within the scope of a competent diy,er. MDF or solid doors can be refinished in a multitude of colours. Probably the most awkward aspect is changing the worktops, depending on if there is a hob unit or sink set into it.
Of course this all depends on your diy level. But its not rocket science, if you are on a budget, and can be done over a few week ends.
A google on the subject should turn up lots of sites that will walk you through the process.
