Where can I find a qualified professional to carry out my air tightness test?

The air tightness tests should be carried out by a person certified by an independent third party. e.g. the National Standards Authority of Ireland (NSAI) or equivalent. Below is a link to a list of NSAI certified air tightness testers.
