When it comes to WordPress themes, you'd run into both free and paid themes. However, it's correct the best themes are premium themes and you would have to pay so that you can buy and make use of them. Some even fetch the developer's extravagant prices - all things considered quality themes take days and weeks to generate.
There are a lot of free WordPress themes out there from various designers but if you're looking for a really attractive and highly customizable theme you might think with the so-called "premium themes". These are high-quality WordPress themes designed by WordPress artists or various companies, they come with an excellent documentation and some of which include their own plug-ins.

You may have to pay a small fee for that annual service but really worth having. If your host doesn't need site backup then all I know is change hosts IMMEDIATELY.
