T-Shirts required - with custom label and printing

We are in the process of opening a clothing company, and we need somebody to supply us with top quality T-shirts. We have the logo ready to go, which we will supply to you. We'd also like custom labels sewn into the neck, rather than just printing it onto a Gildan, or Fruit of the Loom shirt ect.. We need the printing quality to be perfect, as these shirts will be sold in shops and online. Weve had some samples over from China, and the printing wasnt good enough. Were looking for a reasonable amount to start off with. Maybe 100 or so. But will continue to place orders regularly. If you could provide a sample of previous work, that will be a bonus.
