Find Reliable T-Shirt Manufacturer

I want to place an initial run of 100–500 branded T-shirts and I need an experienced sourcing specialist to locate, vet and shortlist factories that can deliver consistent quality at a competitive cost. Please tap into your existing supplier network and industry databases to present me with real, contact-ready manufacturers—not trading companies—who can meet the following parameters:

• Capability to produce 100–500 pieces per style and scale up later
• Transparent unit pricing broken down by size tier, print method, and any setup fees
• Sample availability with clear lead time and cost
• Full production timeline from PO to dispatch, along with shipping options
• Quality standards or certifications the factory already follows (ISO, WRAP, BSCI, etc.)
• Recent client references or verifiable portfolio work

I’m flexible on fabric at this stage, so include any mills or factories that offer common blends alongside 100% cotton. If you have personal experience with a listed supplier, note any insights about communication, consistency, or hidden costs.

Deliver everything in a concise comparison sheet (Excel or Google Sheets) plus a short written summary highlighting your top two recommendations and why they stand out.
