There is just so much wrong here, that i'm having a hard time picking a place to start..
But asking ppl to take someone elses hard work and make it work in what ever skin you are using - Which you havnt mentioned.
Even for personal use, it would be a good idea to ask the creators involved if it is okay to use there work.
then offering to pay for it, the amount your are offering is to mock ppl (creators and if someone would help you) as you clearly have no idea how much time and effort it can take to make things work in a skin. How many hours Skin makers in general is using every year all year.
There is only one way to learn to make things work and that try and try again. Trial and error is half the work.
