Hi, I can do the migration for you, and besides that, see where the issue is, and make it load faster as you wish. Please feel free to check my profile and if you like we can discuss more. Besides that, for caching, if needed I'm gonna use the Pro version for Fastest Cache, not the free one, and for better SEO, I will install the pro version of yoast, which has much more features than the free one. Only the value of this 2 plugins is over 150 EUR, but this ones are free for you. Thank you
