Refine Existing Logo and Create a Small Brand Style Guide

I am seeking a talented graphic designer to refine my existing business logo and develop a concise brand style guide for marketing purposes. Operating within the professional services and technology sectors, the brand has a defined aesthetic that requires enhancement and standardization. The project entails minor logo adjustments, the selection of coordinated primary and secondary brand colors, font recommendations for headings and body text, and a one-page PDF style guide detailing logo application, color schemes, and typography. Final deliverables should include logo files in PNG, JPG, and vector formats (AI or SVG). Please showcase 2-3 previous logo or brand identity projects you have designed and confirm your ability to complete this task within 2 days.
