Taking a Design and coding it for WP integartion.

Hi Guys,

Once again i'm a newbie and finding my feet. I am deisgner who can easily design nice site in Photoshop and even code the html and CSS. What i am new to is integrating this design into WP.

Can anyone tell me what the best place is to start with this all? I am worried if I have enough PHP knowledge and the coding ability and particularly the responsive knowledge?

Also i may be looking for help in creating these sites and if anyone would be interested in making a partnership?

Thanks
