Help moving from Drupal to WordPress

Hey all.

Is there anyone that may be able to help me convert my drupal database posts, categories and users over to the latest version of wordpress at all?

I am willing to pay via paypal for help.

Or indeed, if anyone can point me to some advice where I can try to tackle this on my own?

Kind Regards,
David

P.s
I don’t have the exact drupal version to hand but it is around almost 2 years old ??

Thanks
