Hi. We are a dental laboratory firm in Huntington Beach. We have a list of around 300 emails of prospect customers in our goggle data base. We are planning to launch a mailchimp marketing email ad to these prospects around the first week of January. We need to hire a designer to create a flyer (1 page) on mailchimp platform. Please let me know if you can handle this kind of work. If yes, please provide guideline such as the cost and the timing.
