instagram design/management

Hello! we are a skin care company that is due to launch in 2 months. Currently don't have the product for photography but wanted to start building our audience by posting high quality content. Looking for someone to design a professional looking but fun instagram -like Glossier or Goop orJoanna Vargas. Need some help with creating a consistent layout. I have subscribed to a website with stock images but still failed to stick to an organized grid. Soon will be adding educational posts on the topic of skin care.
Sincerely
