Save For Web in Illustrator is Blurry & Awful - Help!

[PhoePhoe]

Hello

I'm hoping someone might be able to offer some advice, I'm embarrassed to admit that I'm completely out of my depth, I agreed to do a job putting together a digital ad that is to appear on the website of a magazine here in Australia. I've saved things for web previously and they've always turned out perfectly so when I agreed to do this I thought I had everything under control.

My problem is that when I export this file in Illustrator to 'Save For Web' everything turns ghastly, blurry and hideous. I've tried playing around with different settings,

and turning 'type optimized' on and still no luck.

The magazine prefers the ad to be:

Medium Rectangle

300px x 250px

flash, gif, jpg

60kb flash/40kb gif/jpg

I'm probably doing something really obvious and daft wrong, but I can't figure out what that is.

If anyone (please) has any ideas I would be so grateful. I'm including a link to the file if you want to take a look at it and explain to me where I've gone awry.

thank you

Are you saying that when you export, you get a file that is smaller than 1431 x 837 pixels, or something else?
