What better choice to host woocommerce sites?

Can you please advise me which best host plan I should choose for ecommerce hosting sites like woo-commerce:
1-shared hosting
Hosting 2 resellers

My budget is average but I want to provide a fast and reliable service to my client.
I already have a reseller account, but it's the first time I've had a customer who wants to host an ecommerce site, when I've tried the demo of his site on my accommodation, the speed is very low.
SO, I'm starting to think about the options:
1- Host these clients with any shared hosting with others like BlueHost
2- Change my hosting provider with another plan with the same plan (reseller hosting)
3- Change in VPS

Thank you all for your help
