"Thank you for the outstanding job you did. I checked your performance (for a first job) and it’s been really satisfactory. Your professionalism is impressive and I have shared this with the people both in Spain and Mexico. We’re a big company and I’m sure we’re going to have immediate chances to cooperate. I’ll contact you probably next week for new products."
