PS -- how about a beautiful (possibly engraved) picture frame, with a picture of you and her inside? Or a self-made picture frame with a picture of you and her, and a small bottle of Veuve Cliquot with a ribbon around it to celebrate?
 
dude...money doesn't matter.
she's working that day?

make her favourite meal and have it ready for when she comes home... have candles in the bathroom all around (not lit until it's time of course ;) and play some of her fav music during dinner and after. when dinner is over, draw a nice bath for her and depending on what's she like wrt to sex, don't put pressure on her. tell her the bath is for her only and only go in if she invites you.

you don't need to BUY her something. you need to treat her extra special that day.

good luck and keep us posted (within reason ;)
 
Another suggestion if you're short on money: Make it something themed and elaborate where the planning is the greatest gift!

Example: Hide a folding table and two folding chairs in a beautiful, romantic place out in nature. Have a clean, white tablecloth, a chilled mini bottle of sparkling wine (=cheap), two champagne glasses, a bottle of chilled water and two water glasses, and a yellow-frosted mini birthday cake with a candle on it (=$10) and matches hidden in the trunk of your car.

Pick her up and blindfold her, then drive her to the romantic spot. While she's still blindfolded set up the table, chairs, tablecloth, cake and champagne, then seat her blindfolded and open the blindfold when the candle is burning!

Then whip out a small gift ($20) with a romantic inscription. E.g., buy a small gift set with 3 mini sunscreens from a good brand (e.g., Clinique; should be around $20-25), and add an inscription "A little sunshine for my sunshine girl!"). Give it to her, pour her the "champagne", serve the sunshine-colored cake and kiss her -- voila! It'll probably be her best birthday ever.

You can hardly go too over-the-top with women, even the ones who'd never admit to it!

Good luck!!
