Elegant Logo Redesign for Consulting Firm

I'm seeking a skilled graphic designer to revamp our current logo. The main reason for my desire to change is that the current design is outdated.

The new logo should be elegant and sophisticated, reflecting a modern aesthetic while maintaining a level of professionalism suitable for a consulting firm.

Key elements that should be integrated into the new design include:
- Abstract shapes or patterns that add a touch of creativity and uniqueness to the logo
- A symbol that subtly, or directly, represents our consulting industry
- Uses of the hummingbird, our company name is Bastu Group which means hummingbird

Ideal candidates should have:
- Proven experience in logo design, especially for professional services or consultancy firms
- Strong skills in interpreting and translating brand values into visual elements
- A keen eye for modern, elegant, and sophisticated design
- Ability to deliver concepts that are both creative and professional.

Please include samples of your previous logo design work, especially any examples that align with this project's style and industry.
