How to promote model

Hi there

I would be grateful for a bit of marketing advice:

I have made a 3d printable or castable models of the UK politicians for the election
one of them is very successful and people have expressed an interested in buying it

I’m very unsure of how to proceed, I could upload it to Shapeways or start a Kickstarter
but Its only a month to the election but I think if I could get some publicity it would make all the difference

Last time Gizmodo put one of my models to feature but that was not really for commericial use

Any advice would be gratefully recieved

Many Thanks
