Classic Logo & Twitter Assets

I need a fresh logo designed in a timeless, classic style, then carried through to a complete set of Twitter graphics. The deliverables I’m looking for are:

• A high-resolution, vector logo (AI/SVG + PNG)
• Twitter profile picture derived from the logo
• Matching header banner optimised for current Twitter dimensions
• One reusable post template that keeps colour, typography and iconography consistent

The logo should feel refined rather than trendy, favouring balanced typography and restrained colour choices. Once approved, that look must flow naturally into the Twitter assets so everything presents as a single, unified brand.

Although future collateral such as business cards or a website banner may follow, this listing covers only the logo and Twitter graphics. Please include a short note on your design approach and the file formats you’ll supply so I know your workflow fits my needs.
