TL;DR: Charity site opening tonight. Need help with gift amounts/how much would people pay for various prizes? Please advise.Some woodwork starting up today with a giraffe and then a rainbow dash figurine. I'm having to hold off on the rocking horses while I wait for replacement parts for some things in my workshop, notably my table saw straight edge (Who thought it was a good idea to make workshop equipment with cast iron?
Who? Snapped like a twig.

) because I can't angle my legs properly without a straightedge.
However, in order to get things started, the charity webpage will be up
tonight soon, tomorrow I hope; the page is processing. As a reminder, it's going to be for a young Chinese lady paying for heart operations. Keep an eye out.
Right now, though, I need some help with estimates. As you know, I've always tried to give things away or base price on materials rather than time and effort. So I really have
no idea what kind of money these things would pull in real life. But for a Charity thing I want to have the biggest profit margin I can on them, so I want to set the prize bar to get a rocking horse as high as I can without being silly. (Plus, it's gonna cost a bloody fortune just to ship them, which I need to take into account.) So I ask you, what is a reasonable expectation for the price of an MLP rocking horse. It really needs to be at least $500 to make it worth shipping, but should it be more? Should it be 600, 700, 1000? (My heart hurts just to see numbers that big, but it's for a good cause.) I really have no clue about these things, but people spend silly large amounts for the giant plushies.
Help me Obi-wan Kenobi!
Price for the materials + That what you want for yourself = Profit (10%-30% is always recommended) + shipping = Price
Also the price is highly depending on how much detail you put in your work and how fast or to how much people you want to sell it.
A nice gentleman made a Rainbow Dash bed and was unable to get anyone to bid the minimum amount.
That being said, I think that whatever price you decide on should be shipping excluded.
Now, as to dollars: A plastic rocking horse costs about $150.
Given that this is wood, double it for $300.
Since this is MLP, add 50% for $450.
Charity is a factor, let's add another 30% for $585. That's your base price. You can easily play with some of the numbers up and down, however if this is a bidding I'd start there.
And that's my point of view.
