Small Wordpress website redesign with script integration with WooCommerce

Need of a redesign of my Wordpress website with scripts integrated back into site for functionality (javascript, node.js, json). I have the scripts. Site is: [login to view URL] Site w/ scripts turns on the user's computer webcam, they take a photo, and that photo is saved to the WP backend with WooCommerce after purchase….but currently site does not perform that function or load/work well with current custom theme. Site functionality should be exactly the same as this site: [login to view URL] with new sub window popping up or other option if you have creative ideas. Need email capture option if customer wants to download their photo to their own computer for free after e-mail input...of if they wish to upload a current photo. Need simple Scripts I have should do this as well. Looking for Home Page, Pages/Post page and Checkout page/pages. 3-4 Page templates total. Again, I have the scripts and can resend to applicants to see if they can integrate. If you can't make the scripts work then no need to apply. If you can re-write scripts yourself and feel like you can without additional effort then great!:) Site is already up...just not working well with current theme and looks poor. I'm looking for the Home Page to be a “Landing Page” feel but with copy above the fold for SEO purposes. Sites to model after is: [login to view URL] or something similar. Need the site to load fast so no need for large full frame photos or video or parallax effects. Premium theme can be used and I encourage it as I'll need to add more copy to the site as it grows or if it makes the development job easier. I have a Gravity Forms developer license as well as Stripe credit card processing (already on site in WP backend) and WooCommerce already installed. I have SumoMe subscription as well. Looking to have trust symbols on site and checkout page. Can get these once I get a SSL certificate. Ok checkout example pages could be: [login to view URL] I do NOT need a logo as I like the one I have….but the colors currently being used to NOT have to be the same:) Looking to pay for having site completed soon (within one week) with final adjustments after week or after web cam functionality is up and going. Will work/communicate with freelancer to get more specifics after hire. Please be located in North America or Europe and speak fluent English. Site is part of a larger funnel and am looking to hire for more projects upon quality completion of this site. Many thanks for looking and helping me out!
