Composite .psd 3D images for portfolio items.

Howdy, I'm looking for someone to make Photoshop composite .psd images of my portfolio items. I don't have photographs of my work so what I'm after is for someone to use their creative comping skills to make my items look creative, sophisticated, interesting, clean, realistic and 3D. Please see examples of comps attached. I can supply flat jpegs of the elements for the comps. My items include illustrations/graphic design collateral/website/photography etc. I have some pieces ready to go now but will have to filter the rest through as I complete them on my end. I will need the final files supplied as hi-res layered .psd Photoshop files in case I need to amend or print hardcopies. I'm looking for price and lead time per each portfolio comp please. Thanking you, Natalie : )
