Worst case scenario, I will run another Kickstarter or privately fund the Mammoth Riders.
Barry, I'd seriously suggest considering looking at individual figure goals for another Kickstarter. That way at least some of what you've got planned will be funded by the KS. Any goals that aren't then reached (hopefully they all will be though!) would then be less of a financial burden to you.
Theres a community of 50 or so people interested in these figures. Based on your pricing of £5(?) for the foot characters, £5 for the mounted ones and £10 for the Mammoth riders, a total of 9 figures I think it was. I'd guess the next KS would bring in about £1k or so. So setting low-ish goals would possibly make it easier to get some of the 9(?) figures funded quickly.
Will you be having a website to sell this range on, like Dave's Warmonger site? Could you even have a joint venture with Dave, where his and your figures are marketed from the same site? A one-stop shop for independent figure vendors perhaps?
Edit: When you look at the Dogs of War army list, Dave's figures fill the first 4 slots with basic human infantry, your Ogres are in there as well and a Mammoth Rider would make a very nice Tuska model.
