also don't judge on age. My school is a B+E school and I got my enterprise colours before we even got taught. Also I'm top of the class. I know a lot about maintaining a business
I wasn't trying to judge. I have no idea what B+E means, but unless you've started a business, taken a college/university-level business math class, or have taken a college/university-level business admin-type class...it's a lot more work than you know. The only reason I myself know is because my Dad is an entrepreneur who started 6 companies of his own--and has helped me start up 2 of my own.
it costs £13 for me to make a partial fursuit and clothes can be thrown in, I can take requests to wear a certain type of clothes (e.g fairy princess, soldier, etc.)
If I rent out at £10 which isn't an offputting price, then with two rentals I'll be making profits. Also if I do make better and raise the price I can still be affordable and on adverts (easy to put up for FREE) I can write 'prices starting at £10'
also would I do it per hour? £10 per hour?
If it costs you £13 to make a partial, and a partial is all you're selling, you need to keep track of how many hours it took you to make -- divide it by about 3 and make that your per-hour price. Otherwise, you're going to run yourself into the ground with work and never make your money back. Ever. Any business class will show you this.
I would say never just arbitrarily give things away for free -- it might be a good way to get new customers for the first few days of business, but all you're going to end up doing is setting your business up for failure. While 2 hours may pay back your RESOURCES, if it took you just 20 hours to make the suit, then that's still at least £200 that you HAVEN'T made back. You may find it a silly thing to need to charge for, but you'll find out veeeeery quickly that you need to charge for your time.
I would take a long hard look at what the point of this venture is.
If it's just to give making fursuits a good practice, at £10 you may as well be giving them away.
If the goal is to make money on it, you need to be charging a LOT more.
If the point is to practice owning your own business, I'd look up some guides for owning a real business. Just the process of fixing a suit that's been worn through is going to double or triple what you're charging to use is. What happens when the person refuses to give it back? What happens when two people want the same suit at once?
If all you want to do is make a fursuit and have people pay for you to entertain at birthday parties, then I'd charge £15-£25 per hour. Now you need to both make your time and money back from the construction of the suit, AND you need to be paid for the long hot hours in a heavy suit while you spend the effort entertaining people.
These are just my thoughts and opinions. In the end--if you disregard what I've suggested and do it your way anyway, if anyone at all is interested (which if your economy is suffering anything like ours is, there will be very very little interest) this idea won't last very long.
