Help me market my business idea on instagram through professional graphical design

Autodmer is Seychelles' first dedicated second-hand vehicle platform, born from the challenges many face when buying and selling cars. The idea began in 2019 with a simple WhatsApp group and has grown into a trusted community of over 400 members. Autodmer is built on the principles of transparency, trust, and security, ensuring buyers and sellers have a reliable space for their transactions.

For now, we have an active WhatsApp group and an inactive Instagram account. I want to revive the instagram account through the use of high quality content
