Graphic Design Request – Logo Refinement and Social Media Materials for Aqua Diary

I'm looking for a graphic designer to collaborate with me on creating promotional materials for my web application Aqua Diary (https://aqua-diary.com/) – a digital journal for tracking aquarium life.

Scope of work includes:

Refining and adjusting the existing logo (SVG file):

Style improvements and potential suggestions for enhancements.

Creating promotional graphics (banners) for social media use:

Facebook (cover, post, optionally stories)

Instagram (post, stories, optionally reels cover)

Graphics should be consistent with the theme of the application (aquarium, water, nature), modern, and visually appealing.

Additional information:

The app is aimed at aquarium hobbyists and owners – both freshwater and marine.

This can be a one-time collaboration, with the possibility of future work on additional materials.

I'm open to creative suggestions – I'm looking for a fresh visual perspective that fits well with the aesthetics of the aquarium niche.

Please include in your response:

A portfolio (ideally with similar-themed projects)

An estimated price and timeline for completion
