Hi Angela,
you just need an oligo which contains the T7 promoter at the 5' end and some
specific, complementary bases.

Here's what my primers looked like:

5' T7 promoter                                                             3'
gtaatacgactcactataggg-20bp of complementary sequence of the 3'-end of my gene
20bp of  complementary sequence of the 5'-end
-> PCR -> in vitro transcription

Please tell me, if you need more specific informations.
