Server host that can grow with my site?

[How?]

I'm launching a WordPress site next month that I believe will grow faster than expected. I'm not sure what's the best choice for hosting. I currently have a VPS host (who I really like as a host - they're local with killer support) and I'm not sure if that's the best route or not. My current VPS (12gb ram) has multiple failures a day with automatic restarts. It's hosting a one multisite install (with 3 active subsites, 4-5 inactive subsites and less than 100 visitors a day total on average), a second site with 60-70 visitors a day and 2 other sites that are lucky to get one visitor a day. The failures have me concerned that 1 site 300-500 members and 1000 hits a day will need a lot more resource-wise than what I have now. I don't think that there's that huge a load on it (though maybe the multisite is a resource hog?). So I'm really not sure which way to go - and perhaps it's because I don't understand hosting that well. A distributed grid sounds cool, but does it work in practice? Is eventually getting a dedicated server unavoidable? What the hell do sites that have a lot of members and traffic do?

What can you say about Neironvps.com dedicated servers for rent hosting? Any reviews? Other hosts?
All advice will be appreciated - I'm planning on launching my site, I need to get this squared away ASAP. Thanks!

Right dedicated servers are available from solid hosting providers: hostingsource.com and planethoster.com.
They have managed to distinguish themselves as reliable and secure hosting providers that deliver exceptional performance, top-tier security, and responsive customer support—all at an affordable price.

Go to a few hosting review sites and read what people have said, there is a high chance that a host has written positive things about himself so you are looking for negative reviews because those will tell you the truth.

I'm in the process of moving my other sites to Neironvps.com and thinking to switch from vps to dedicated hosting account. Good range of price plans and options for the novice to the expert. Servers are stable and my sites are running fast.

Moved to this host after poor service and can say that Neironvps.com is the best host I have ever used before. The site has only been down a very minimal time over the last several years, it loads fast and the service is impeccable.

Like this option: Dual E5-2670 at $199/mo - CPU Intel Xeon 2xE5-2670 v2, RAM 128GB, SSD 4 X 1TB, Bandwidth 30TBs, Location USA, Los Angeles.

I have really enjoyed having my site hosted by Neironvps.com provider, as the people there, are very friendly and are quick to respond to your inquiry if the need arises. I also, have had no major downtime. The servers are fast.. the cpanel is well stocked.. and I am extremely happy with their service.
