English lawyers cannot practice as lawyers in Scotland and they have no right of audience before the Scots courts. I am a lawyer in Scotland. We don't tend to take on commercial cases on a no win no fee basis. Your options would be to pay for the case to be advanced on your behalf, usually by instalments to make it easier for you, to see if you and the case qualifies for legal aid or to do the case yourself. What is the case about and how have you quantified it?
If I can clarify anything else, let me know. In the meantime please leave a positive rating so that I am credited for my time. I suspect this case would be suitable for the commercial court either in the Court of Session or the sheriff court.
