Help to buy RE-mortgaging Help please

can anyone recommend a help to buy remortgaging service? Preferably one that does help from start to finish

I’m based in Cheshire but I’m not bothered where it is as long as they are efficient and know what they are doing – a few neighbours have used the local solicitor/financial person and he’s been next to useless

if anyone does it as a job or knows someone/company that can help that would be amazing

much appreciated- as it looks a nightmare to sort out and it’s due in 6 months
