Sorry if this is a little obvious but why don't you call a few and make enquiries, they all have the required knowledge and qualifications to assist you, some will be busier then others, some will be solo operators, some in a company, your choice as to who you go with.
As this is a public forum, I thought someone here could recommend a company they have used and been happy with.
As I have a mabs voucher, there are only a few companies that will accept it. I have gone through the list of pips that mabs supplied me. Some of them didn’t get back to me, there were a few on the list and their contact details were gmail address. Only GT got back to offer advice but are looking to take over my finances for 6 years.
I really require a solicitor and not just a pip practitioner.
