Hiding fields and changing field title on Add a job page

I would like to change the title of the field "min budget" to Budget per hour - I have searched the plugin files but can't find what to change.

As well as this I would like to hide the fields "max budget" "completion date" and "attach specs for extra information". I have inspected with firebug but can't find the correct css class to hide this....

Thanks, btw I read on another thread that a custom fields update is in the works, any news if its imminent?
