Getting help Prototyping

I have some experience prototyping but i need someone to lead me the way as when i am talking g tutorials and practising the prototyping i understand everything but when it comes to have a Psd and coding it i am having problems and getting into panic mode.
I am looking for a personal tutor that can lead me and practicing under his supervision, if anyone can help me let me know it and we can talk about prices
Many thanks
