This is my very first post here and while I'm fairly certain this is the right place for this post I apologize if I post incorrectly or break any rules.
Basically I'm looking for a game programmer but before I post a job posting I need to gather some info.
What I'm looking for is a programmer to create a small 3d demo consisting of one or 2 rooms with interact-able objects. It would be first person with normal WASD movement but something like "manually controlled arms". Essentially pressing buttons would increase or decrease the angle of the upper and lower arm and another button interacts with objects like a door which can be opened and objects that an be picked up etc.
I've done some 2d programming before however because I don't have experience with 3d programming I don't know the difficulties of this task. Getting a character animated and 2 rooms up wouldn't take that long but I don't know how difficult manually controlling limbs are. Also it would have to be done with a completely free (no commercial license option) game engine.
So I have two questions based on the task. All opinions welcome
1) How would you rate the difficulty of this task?
2) How long do you think this task would take full time as opposed to a part time hobbyist
Now comes the business side. I have seen salary information on game programmers but because this is a small demo I'm not sure what way to go with it.
So here is my question. Once again All opinions are welcome. Keep in mind I have limited funds. Assume that I didn't choose the hire a hobbyist route
3) Would you pay per feature, per hour, or a 1 time payment? And how much would you pay? or what do you think a game programmer would charge?
Much of my difficulty comes from the first 2 questions. Because I don't know the difficulty of this task and even a slight clue on how long it would take, I have no idea if I should try to get a hobbyist or pay someone. And if I do pay someone I'd rather not pay someone a lot of money for what could be simple task. Lack of information is financially fatal so I'd like to thank you guys in advance for helping me out.
