Small graphic design work + resizing photos

Hi designers, 1) I need the circle design (see attached) reproduced in a high quality image. Final copy in .png The color needs to look as gold as possible ( not sure what hex color is best) 2) I have 14 interior design photos that I would like increased in size as much as possible WITHOUT LOSING QUALITY. Time: 1 day I have much more work, so if you do a good job for me I will use you again! Thanks!!!!!!!!!!
