app with website

I am seeking a freelancer to develop an app with a website that will allow me to sell products/services. I have a detailed list of specific features and functionalities that I would like included in the app and website. I prefer that the app and website be available for both iOS and Android, with the website being available on PC. I am confident that a very professional and visually appealing product can be created that will meet all my needs, and look forward to hearing about proposals from freelancers.
