Try All-Aspects their pool guy charges £105 p\m to do a proper job,also for any other work try them for a quote,we have used them for a few jobs and the prices are very fair and although we live here and can arrange our own workmen it does take away the hassle of chasing up bad workmanship,haggling for a realistic price and just making sure the workers turn up.
We can highly reccomend them and they are great people,will be doing more business with them in the future.
