454444 easy banner design change colour

Hi All, I have a banner that i have uploaded and i need the colour to be changed. i require about 20 different colours in this banner. Where the banner is red, this colour needs to be changed to other colours and the background colour (gold) also needs to be changed accordingly. I will leave the colours up to you to choose as im just looking for variety. i know the file is not the best as i have condensed it down to send over. Im looking for a long term guy who i can send work to regulary as i have about 10 other banners that need this type of work to be done to them. before i accept your bid i want to see a banner with its colour changed to makesure i know that you can do the job. Hope to hear from you soon Regards
