Only thing I can honestly say is I think you may be a tad high on your set of two trades. And by a "tad", I mean extremely high.

I mean, In Stock Trades,
HERE, has the Miller one for $9.34 and Blood for $7.12 = $16.46.
I guess you may get a guy that cares if it is a first printing, so crossing my fingers there for ya, but you usually have to offer a pretty good deal for trades on EBAY as Amazon or InStock is just gonna be a better deal.
Still waiting for your comics however
