I'm looking for a detailed quotation for plain shirts that consist of at least 70% cotton. The shirts are intended for printing, so it's crucial that the fabric quality can handle ink well. Please provide information on the available sizes, colors, and any minimum order quantities. Additionally, I'd appreciate it if you could include pricing tiers based on different order volumes, lead times for production, and the possibility of samples. Looking forward to your prompt reply so we can potentially move forward quickly!
