social media exccutive and crousel designing , email template designing

My project is to create a series of promotional email templates that I have a design in mind for. The purpose of the templates will be to use them for marketing messages. I'm looking to have the templates designed with a sleek design that incorporates my existing branding. It is important that they follow all of the industry standards and are compatible with multiple email platforms. The templates should be easy to customize with colors, fonts, images and text. I'm looking for someone who can create templates that will engage my customers and help increase my sales.
