Export Question. Weird Frame Size request and small file Size from MC?

So, got a weird request for a corporate gig im working on. This might not be weird for some of you guys, but usually i deliver same as source for 98 percent o fthe work i do. The other precentage i know how to deal with.

Anyways. I have been working with 1080 24p 5D MK2 files. Edited in MC in 1080p, dnxhd 175.

Got to the point where were taling about delivery and the company wants the files in

320 x 180 and under 20MB... now some of these files are 1:30 in length, but range to about 6 minutes. I have 14 of these to export.

Whats the best way to go about this. I have Compressor, Squeeze, Mpg Streamclip, Adobe Encoder. Im think export a QT ref, but what then? I just did a test in Compressor, and for 1.5 gig file, it got down to 68MB using the youtube sharing preset after i customized the frame size?

Any help is greatly appreciated, im sure its a no brainer, just nothing ive come across since i started working in HD
