Need Help With Postcard Mailer Design for Commercial Real Estate Business

This is what a business in United States was looking for in their postcard design

I am wanting to create a 6"x9" mailer. Double sided. Horizontal layout. My primary color is blue. I also have white, black and even gray. Attached is the text I'm wanting to have on the mailer and I have the text separated for both front and back. I specialize in industrial real estate so if any graphics were added it would have to be a very nice looking warehouse.
I really do not like emojis/icons
I don't want this to be too busy
I do want it to look very clean and professional
I think a warehouse graphic adds strong visual appeal and enhances the overall look of the mailer.
