Modern Logo Design for TransFactor

I'm in need of a modern and clean logo for my company, TransFactor (Trans stands for transportation, Factor stands for the purchasing of their invoices). Our business targets trucking companies, and we purchase their invoices. The logo should reflect both these elements equally - the trucks/transportation aspect and the invoice/purchasing component.

Key Requirements:
- A modern and clean design style
- Equal representation of trucking and invoice purchasing elements
- Creative use of color (any, as you see fit)

Ideal Skills:
- Graphic Design
- Logo Design
- Brand Development

Please provide a portfolio of similar work if available. Looking forward to your creative proposals!
