Mug press with a large element for bottles sublimation?

[Wika]

I like to expand my products and I am thinking to start with water bottle sublimation. The thing is I have the FreeSub double mug press and the only option I have with this machine is just wrap the water bottle in lot of normal printing paper until the bottle finally fits on the 11oz mug press element. The result is not bad, but not good enough to sale them. At the moment I am only looking for a mug press. I don't have oven and is not in my plan buy one. That is I would like to know if anyone knows here in UK is anywhere I can buy online a mug press with a large element for water bottles. I know Brildor store in Spain have for sale, but is not affordable if they need to ship over here.
Thank you in advance
