photoshop image editing

***************** READ BEFORE BIDDING, Budget $30)*************** I have a small project of about 90 pictures that needed little touch up and editing. all the images has same issues, so it's repetitive job. check attachment for reference. first, in the golden unit, there is a little piece of metal missing at bottom of circle, need you to work that out in order to match with the rest of the item. second, the dark brass unit you'd need to make the picture simply better looking, increase color so on... need you to work on the item itself, not the background please make me few samples so i can judge your abilities to do this project properly
