NEW Single Line TTF Font required (from Double Line current)

Seeking a skilled typographer to convert a provided TTF into a single-line font matching prior work on Helvetica single-line format. Deliverables: production of a clean, vector single-line version suitable for use as a new TTF file - just with a Single Line, rather than the current double-line standard, tested for consistency and usability. Must preserve glyph integrity, spacing, and kerning where appropriate. Would request the whole alphabet, numbers and special characters. Provide a firm fixed quote and estimated delivery timeline. Modest but fair budget; professional quality and clear milestone-based delivery expected.

Please note: I'm having difficulty attaching the current TTF file, but I do have it and can share the best way you see fit if you take on this project.
