UK based Infusionsoft specialist

We are looking for a UK based Infusionsoft specialist to give general support and also help out with specific problems such as a current issue where we wish to contact customers who have opted out of our marketing campaigns and ask them to opt back in. We need to run a report to find all current customers who have booked to travel with us, have not yet gone on their trip, but have opted out of our email campaign. We need to do this so that they will still receive automated and follow up sequences from IS relating to emergency information on destination and feedback/reviews.
