Graphic Designer

So far I have had six different graphic designers edit my logo and its very visible to see changes still need to be made (you may need to zoom in). I assumed the graphic designers I hired would take more pride in their work and pay closer attention to detail. I'm too busy setting up a business to double check over work. All I am asking for is a competent Graphic Designer to edit/clean up my logo design, erase the mistakes, make sure lines are symmetrical, no random colours in certain areas.... Clean and symmetrical.

I will attach the original files of my logo for you to tell me what it is exactly you would change, this way Its clear you know what you're talking about and I'm confident you'll do the work to a level that should be expected.

Brief in short - Just edit the logos with the black and white backgrounds , ignore the designs with the blue background.

1- Please change the clock hands to a truer yellow
2- Please amend any mistakes you see.
