In Dubai there is one called Blue Rhine, they deal in acrylic sheets and all types of signage. I bought these for my own restaurant. You can cut and bend it yourself using handsaw and heating equipment. But I would recommend you seek the help of the company people, because they have been doing this for years and know that very well. 

I would go for sand and cement because not that adhesives are bad but they can lose strength in time when exposed to the weather. Whereas sand and cement has proven to be a durable option.
