Angular 4 Coding - vCD (VMware) Plug-in

Need to modify an Angular 4 Code that includes VMware vCD UI publish extension (vcd-ext-SDK you can learn more using this link: http://www.vkelby.com/2018/10/vcd-ui-extensibility-api-client-part-one-preparation/ and part two
). The code is complete but needs small modifications.
To avoid any miss understanding below the terms:

1. Skype to discuss and demo what needs to be done
2. If you happy with the work will share the code
3. Payment after you show a complete code or demo or screenshots
4. Regular updates

Thanks
