I think every WordPress site should have a child theme, because it is a great way to organize all of the customization. Once in a while, you might need to update your theme, if you have a child theme, you will not lost all of customization that you have done, because you did all of the customization on Child theme, so updating parent theme will not effect them. Therefore, it is very important to have a child theme, and it is best to apply it when you install the theme for the first time or before you do any customization to your site.
With this gig, I will create a child theme for your theme. As you can tell when you look through my profile, I am the only one on Fiverr that have been working on WordPress for years and I am really experienced at any WordPress issue. I am not just saying that like other gig promoters, most of my current clients can prove it, just look through my profile. : )
As usual, this is only for one site per theme per gig.
