Hi. I'll be pleased to help you setup your theme and configure as necessary for you. Most of the themes come with demo data but I would have no problem loading up a few products manually and providing any documentation or instructions you need to move forward.
When you have the theme selected, send me a link to it as well, so I can confirm that it supports the latest version of wordpress etc. Also do you already have hosting and a domain name in place? For multiple languages, you will most likely want to use a paid plugin such as WPML or another, and it will be a good idea also to choose a theme that has this type of support built-in.
I have a total of 10+ years in the IT Industry including two Microsoft Professional Certificates and have been working with wordpress and other cms platforms for the past few years. Also, please take a quick look at my profile/feedback and you'll notice I'm a 100% trusted freelancer, a reputation built from perfect accuracy, attention to detail, excellent efficiency and great communication. I strongly believe I'm the perfect candidate for your job and you can be confident knowing you've hired a professional who delivers on-time.
Thank you for reading my proposal and I look forward to hearing back from you toward the start of a healthy working relationship. I'm from the Caribbean so there's no language barrier between us and our time zones should be close as well. Kind Regards, Kenny
