Okay I am already regretting my sarcasm. Obviously video producers are (quite reasonably) in this business to make money, and thus the longer the clip that is given away for free, the less likely one is to part with ones money.
So TIB here is an idea. Why not preview clips by a combination of the photo montages (that you already do) accompanied by a REAL Audio preview soundbyte of say a minute. That way prospective punters like myself, can See whether she is ones type of Ticklee, as well as Hear whether she has a melodious laugh (which I love), or a screeching/screaming laugh (which I hate). Thus if the propective customer likes what he sees and hears, he will have to fork out (purchase) to get the actual moving joined up version.
