Skilled Photoshop artist required

I have an poster which I have made through a designer (attached). Would like a proficient photoshop artist to help make cool looking changes. Would him/her to: - Change image at end of doorway from a sky/clouds to amazing looking light bursting out or beautiful looking like at end of doorway. - Make the stamped words "free handouts" look more like a stamp. - Improve general quality of poster (i.e. text positioning and style). As the bulk of work is complete and I am not asking for something to be made from scratch, I do not wish to pay too much.
