Snagging surveyors

I am due to complete by the end of February (that probably means 2008)! Anyway I have been in contact with a company called P.S.I, via email with Philip Nott. I  was wondering if anyone has had experience of using a company called P.S.I. to do a snagging survey? If so please can  you let me know your experiences.

I am concerned that I cannot get out to Spain much prior to completion and will have to rely on such a survey when asked to complete, especially if the survey  suggests that I should  delay completion.

Any help and advicein  would be useful.

Thanks
