Actually I understand completely. It's not easy, that's why you're here touting for someone who has spent time practicing the skills to do the work you can not. If you were a plumber and I asked you spend your free time replacing my boiler, would it make you feel better if I told you it was easy? You are asking for help, it does not do to undervalue the skills you lack.
We get people who pop up and request models, pictures, photoshop mash-ups and so forth every week. You may get lucky and someone is interested enough by the idea to spend their free time doing it. However, it's my job to be unpopular and point out that if no one takes up your offer of free work, dont be surprised and dont pursue it. There's nothing stopping you having a bash yourself, and you're much more likely to get help and encouragement posting your own attempts.
