Hello there,
I have read your project and i'm very interested. I have had a lot of experience in Social Media Marketing and i've learned that this can be a great tool towards success sales.
In promoting a graduation supply website, i would start by research of universities, find out graduation dates, from there, i would make sure i dig deep into social media, find out graduates. Use tools like instagram and follow hush tags to target specific people, get to youtube and find related videos, find web influencers. I would also suggest SEO as a tool to use.
Chat me up so we can discuss the details of the project.
I would love to take part in it.
