Custom Theme Solution for more than 500 products in Woocommerce

As we all know that most of the users with more than 500 products in woocommerce are facing high CPU usage issue. And, the wordpress themes available here are not appropriate for every niche and not easy to customise for most users. Hence, is it possible to get a custom theme with the help of freelancers which is compatible with Alidropship wordpress plugin?

This might be a dumb question, but I am not a coder, hence I am not sure about this possibility. As a store grows and require more products, this solution might be the best for most users who are able to spend for a customised theme.

What could be the drawbacks of this solution (if at all this solution is possible).
