Dear Alex,
It was really nice to meet you yesterday, and we are really glad that you could come to our factory.
I hope that your return to your office went well.
I will certainly visit one of your shops very soon, so I can have a better feel on what you are doing. We have some customers who might be interested in top end accessories.
Please find attached the order confirmation for the job we have discussed yesterday.
Should you have any question, please feel free to contact me at your convenience.
I remain at your service, and look forward to our next meeting
