Check the easy fixes first:
~Skewers tight enough? (I just spent more than $300 on parts, and my creak ended up being a $#^%$ rear skewer that was working loose under my mashing. (And I was POSITIVE it was the BB.))
~Headset parts & bushings clean, lightly greased and properly torqued?
~Does the sound happen when you pedal standing only or while seated also? Only while seated, but not while standing?
~Try pedaling one legged and while sitting up with no hands on the bars.
~Put a drop of Tri-flow (or your favorite chain lube) on each chainring bolt mount point between the large & small chainrings.

Good luck and keep us abreast!
