Hosting support

I have been working with Commerce Kicktasrter 2 to use all the nice feature that we have in Commerce and above all in Kickstarter, but we have seen that Kickstarter Commerce 2 consumes a lot of resources and that with a regular VPS hosting we could have a bad performance for browsing due to all the resources that are consumed.

We want to have the speed that this demo have here: http://demo.commerceguys.com/ck/ and better if possible

Performance with CCS and Agregation have been activated and we can add Boost and maybe Main Cache. But we would like to know what hosting can you recommend to manage this kind of Commerce Kicktaster 2 with Managed Service and Cpanel.

We have thinked in Linode (But it is unmanaged as I guess). Maybe one VPS for MySQL and other for Web Server. And maybe use APC and Main Cache.

Please let´s know what can be the recommended hosting to provide good performance for Drupal Commerce and above all Kickstarter Commerce 2 as you have at your demo site. We don´t want to spend a lot in VPS and we have estimated an average of US$40 in Linode Hosting for maybe 2 VPS of US$20 each one. One for MySQL Server and other for Web Server only.

Let me know about the proper hosting for this Commerce Kickstarter 2 without investing so much money in VPS,

I am about to develop a web portal with few thousand users with normal content types, calender and video sharing.
I am new to a large project and chose drupal 7 for it. I have worked on it for smaller websites.

I have to deveop a video gallery. some videos are free some are paid.
I am thinking of doing it 2 of the following ways

I'm having problems after moving a Drupal website to a new server. Initially, no assets were being loaded correctly as Drupal was trying to load them from an URL such as this:

http://www.my-drupal-website.com/css/...

I would like to know which is better if we are working mainly with Drupal websites (price, performance, easy to use, etc)?

Thanks!

New to drupal but am currently developing a few new web sites locally using Drupal 7 and Postgres 9.2 on Ubuntu Linux. Hopefully I will have these sites ready to be published in a few months so I need to start figuring out the hosting aspect. At least for the first year or so, traffic on both sites should be somewhat minimal (50-100 hits a day) so shared hosting environments is perfect. One site will be more informational with some user interaction while the other will be an e-commerce site.
