Which Hosting Provider to use for Wordpress theme live demo?

I got the soft rejection on my WordPress template and I have resubmitted It, 99% It will be approved but Now I want a suggestion for Hosting. All things currently setup on Hostgator Shared Hosting but I am worried about It’s Speed. Let me know your suggestions, please. Thanks a lot in advance.

We are using inmotion hosting. It’s good, but it has resource limitation

Is that shared hosting or VPS?
