Professional Graphic Designer Needed for Web Banners & Social Media Launch

Hi there,
I am looking for a high-level, professional graphic designer to create social media posts (Facebook, Instagram, LinkedIn) and marketing banners for my upcoming website launch.
To be precise: I know how to use Canva and have already created some basic concepts and layouts myself. However, due to my demanding full-time job, I simply do not have the time to execute this. I am not looking for someone to just copy what I did; I need a professional designer who can bring real creativity, strong corporate/tech aesthetics, and independent execution to the table.
Our website is launching this month, so we need to get everything structured, polished, and ready under a tight schedule.
What I need:
• Complete design of social media grids and posts (FB, IG, LinkedIn).
• High-conversion marketing and promotional banners.
• Total autonomy to take my basic ideas and transform them into premium, professional visuals.
• Fast turnaround and strict adherence to deadlines.
If you have an established portfolio in tech, retail, or B2B design and are ready to deliver enterprise-grade work this week, please apply with your portfolio and rates.
