Magento 2 coaching

Hi, I need some coaching on Magento 2 community edition theme creation to get me started. I want to create a new theme for my website, based on Luma, with the frontend configuration of the Luma sample data site. I want someone to walk me through the process for creating the new theme and doing a minor home page edit, on their own system, with me observing via Skype, and asking questions as you go. It will probably only take an hour or two, as I just want to see how to get started, and how to recreate and edit the existing layout, and I'll be able to take it from there myself. I do not want to edit the existing Luma theme, I want to create a new theme, that inherits from Luma, then extend it to recreate the sample data layout. I use a Windows PC, and have the website on a shared hosting provider, so the demonstration should use appropriate tools and techniques. You will need to have very good Magento 2 skills, implement best practices for theme creation, and be a fluent English speaker. Ideally I would like to schedule this for today. Regards Dan
