We got our last lot of stuff from Phoenix Workwear, including another 15 polo shirts.
Ayyaz has always been helpful and prompt. He was able to give really good advise about embroidering our logo onto the tops, jackets, and so forth too. No minimum order, as far as I know, but there is an initial artwork charge, like most places, which is what will bump up the cost.
Phoenix Uniform Company Leeds (he's having his new site done just now) - telephone 0113 245 5050 for a brochure and samples.
IMO, it isn't worth printed shirts costs - they look shabby really quickly.
We issue work boots, trousers, Polo Shirts, Jackets, and we're looking at some sort of jumper and a shirt too. We toyed with the idea of ties for sales, but decided white shirts with a small logo on the pocket was probably better.
Until now, we've not put the logo on the trousers, but I think we probably will next order on.
I just think if it's worth putting your logo on, it's worth a bit of quality as it will reflect your business one way or another.
