Sleek Minimalist CPA Logo Design

I'm looking for a professional and minimalist logo for my CPA practice. The logo should use soft colors, like light blue, and should convey stability.

Requirements:
- Use of initials or letters, and a symbol or icon
- Soft color palette, primarily light blue
- Sleek and professional look, similar to Grant Thornton or tech startups

Ideal Skills:
- Strong portfolio in minimalist design
- Experience with professional services branding
- Ability to create a cohesive and modern visual identity

Please provide samples of previous work.
The business is called Lumos CPA Professional Corporation but will ultimately be marketed as Lumos CPA. Attaching some examples of ones I like for reference (the first five logos from the top. Not so much the rest) Would like the logo to be minimal, yet recognizable.
