Dear sir, I am experienced wordpress site maker. For examples of my works you can see my portfolio.
So, as I understood from your explanation, you only have site template, and need a person, who will add content, replace images and icons.
I can do this job for you, but I'm warning you from here - Icons, pics, etc are easily costumisable if one knows it. But, there are more complex things, which might brake theme. So, if you award me and explain in details what do you like there and don't I will tell you exactly what can be done and what is better not to touch.
I also will make standard security and SEO checks for your site.
