asking for a trial version + supporting RTL languages

Hello

I'm working in a business env. I have to try the product before purchasing.

We chose th personal version , but is there a trial version ?

since we use Arabic Language in our website , I would like to ask if it's compatible will with RTL languages ? ( RTL : right to left direction )

==
The other thing :
is it possible to use the plugin to add Custom post, for example :
designing custom forms that add a new product and save the result in a database .. ?
==
all in all , we need a trial version .

Thanks
