Apparently, I need to find developers who will not only work with web design and site navigation, but also help with the launch of the online shop so that everything goes smoothly. Any recommendations?

Of course, I'm thinking about my own online business, but I'm unlikely to get to that anytime soon. There are great opportunities for growth right now though.

When it comes to ecommerce businesses, finding developers depends a lot on the platform you plan to work on. Among all the options, WooCommerce seems to be the best, and it's great that you can find experienced developers on amasty site who will just help with everything you've listed. It could also be additional services in the form of selecting extensions and plugins and installing them.
