Landing page with checkout, Angular, Typescript, css is a must have

Please do not apply without:
HTML, Angular, Sass,Css, Knowledge in UX UI

Currently I have the theme bought (base html, css, the design and the will be it )
It is not needed CMS
All text info can be in HTML

The Task will be:
1 - Organize the landing page, with menu and contents, theme done, just put text and adjust css, from wireframe
2 - A checkout screen, with steps, with payment gateway integration (backend done, ready to integrate)
3 - A contact screen, with form submission, integrated sending to an email

I will provide, wireframes and reference, and zip with the theme.

The definition of done is:
. Landing working, checkout working, contact working, and all follow the wireframe
. Only adjustments or changes of wireframe, can be negotiate new checkpoints


Thanks
