Slanj are good, quality and have a knowledge about what they are doing.
I ordered a Kilt from them a while back and there was a delay at the mill weaving it. They were sure to phone me and give me an exact timeline and gave me a full refund when I told them it would be just too late.
The staff are friendly and the Kilts are good quality.
They are, however, expensive.
You might be as well using one of the Kiltmakers on this forum or one of the sponsor stores.

Good luck!
