Problems Obtaining Provisional License

hey i wonder if anyone can help me. i applied online to get my provisional license application through the post, they sent me a letter saying i need to provide ID.

Now, this is the list of ID which is acceptable;

a current and valid passport
a biometric residence permit (formerly known as the identity card for foreign nationals)
a UK certificate of naturalisation
an EU/EEA national identity card
a travel document

i dont have ANY of the above. i did a price on the uk certificate of naturalisation and they want £85!!

Could anyone provide details on the eu national identity card on how i get one and how much it is as i did a google search and there were loads of links all for different ID cards.

Thanks, Dan
