Is there any sampling specialist or PhD student out there who could provide itsy-bitsy advice for me at the end of a phone or email for the next few weeks, to comment on some reports I am preparing? Confidentiality essential. I could pay a small honorarium plus fee-per-call (or would reciprocate by providing similar services). If interested, please email a 10-line CV plus full contact details including landline and mobile phone numbers. JOHN BIBBY (York, England)
