Dear Joseph hall,
Thank you for your interest in the work that our firm does for interior designs. Moving forward with our dedication to providing the best possible service and continued support for our potential customers, we would like to invite you to our open house event for one of our model homes late next week. We hope that by taking part in it, you will be given a better idea of the quality of work that we are able to produce. Give me a call at 888-8888 so that I can schedule your visit. We look forward to hearing from you soon!
