Wyeast is a company in the US. The past couple of years I have been using their liquid smack packs. They have a dry and a sweet mead yeast. I didn't find a difference in them yet. They also have a cider yeast we are trying out this year.

Not sure if they would ship out of the US. I have used Northern Brewer and Midwest Homebrewing Supplies. Both ship to me pretty quickly. I am in Wisconsin which is the next state away from them.

Many people use dry yeasts and are happy with them. EC1118, BM45, and 71B are popular ones. I think it was the 71B I used in the past.
