Because of I do not know about the theme that you have chosen yet, I cannot give you a exact time for my work period. At most it will take 2 days, but I think it may finish in a day. After seeing the template that you have wanted to clone, I may give you the exact time.
I am going to design the page that you want and I will provide you all the required files for a template. Also, I will code the required CSS and other PHP files for the template.
