Hello!
i'm looking for someone who could do this for me in the next couple of days please. Please let me know what you would charge. Many thanks!

If you find yourself getting no responses here  (especiially in this section) I found through websearch that Camberwell seemed well provided with ads for suitable firms.  That was after non-response to  two emails to an SE22 solicitor.  No local knowledge to offer though., I'm afraid.  In the end  a remote witnessing was arranged for me.
