Where can I get reliable altcoin volume info? Not 24 hour volume, but longer

[vuduchyld]

It doesn't seem like too much to ask, but then again, there are so many exchanges it's like the Wild West out there.

I've tried:
http://www.crypto-coins-table.com/index.php

http://coinmarketcap.com/

http://www.cryptocoincharts.info/v2/

The ONLY thing I can find is 24 hour volume.  Let's face it...24 hour volume is meaningless for alts.  I really need to find 20 day volume or 30 day volume for my specific purpose--preferably 30 day volume.  If I could even find raw data in some kind of excel or csv table, I can extract it.  Not sure about API, but I could probably find some help of figure it out. 

Any ideas out there?  Help!

Sorry if this violates convention, but I gotta bump for the day shift just this one time.

Help me please!

Doesn't Poloniex have a long graphic about volume? Im not sure about the rest of the exchanges tho.
