I need help creating professional visual content for social media.

Hi, I am soon to launch a new European automotive business and will need help building my social media presence. Things that will need to be designed. 1 - Cover photos & profile photos. 2 - Advertisement posters advertising my services. 3 - Flyers I have unlimited future work available to anyone who is easy to deal with and does a great job. My website will be live soon which I will link to anyone who is interested in this job. The business deals with cars such as Ferrari, Mercedez Benz, Audi, BMW and other big European automotive brand names so all design work but be to a very high standard.
