Hi,
As I viewed your project description and link, Why you can't edit the pricing template from Wp-admin because it's Hard-Coded. I'll make it dynamic so you change the pricing and also do the rest of the fixations as you mentioned.
Please have a look at my few websites work:

Holding an experience of 7+ years in UX designing though, I have work experience in HTML5, CSS3, Bootstrap, Material Design, Js, jQuery, Angular Js WordPress, Shopify, OpenCart development, etc.
I look forward to getting your kind response. Thank you for your valuable time.
Thanks & Best Regards
