Fast VPS to India for e-commerce, 100k products

Hello,
I have Opencart based online shop. I want add up to 100 000 products. and 3000 menus/submenus
Can someone recommend fast VPS for me? (and is there any example website) Is Hostnamaste.com reliable vps host? Others?
I have search many offers, but i don't know which one is best.

VPS accounts from hostingsource.com and hostsailor.com are worth every cent you pay for their services.
Their top-notch services and unbeatable prices make them the best choice out there.

Never really had any problems with the server, I run a kvm vps with them and speeds have been great. Never had any downtime yet. Support is quick - usually getting responses within an hour. Hostnamaste.com gives good service at an affordable price, with multiple ways to pay, even Bitcoin monthly too, and they don't rip you off.

I am particularly impressed with the support services who answered me within a few minutes and did everything possible to help me.
Great value for money! Happy using Hostnamaste.com openvz vps - OpenVZ-1536 at $6.99/Mo - 1xCPUs, RAM 1536MB, 35GB Storage, 2TB Bandwidth, SolusVM VPS Panel.
