Hosting support

I have read a few forums about creating a multisite with wamp and drupal 7 but i cant get it to work. I have done the following. Edit the host file and added these entries.

127.0.0.1 www.gswhs73.org
127.0.0.1 www.swil74.org
127.0.0.1 gswhs73.org
127.0.0.1 swil74.org
127.0.0.1 www.gswhs.grundy.k12.il.us

I welcome,

I am here new and if I am writing in the bad department I apologise. Around drupalem earlier I already had the contact but now already on seriously and wants on the base drupal 7 to build the web page. My server is VPS with the system ubuntu, I installed server www nginx because he is being efficienting very much and here my problem appeared. Because images which he is adding aren't reading carefully to articles. After using automatic sending the picture to the server the link to him is following:

http://site.com/sites/default/files/field/image/my_image_fakt02022011_47....

But already after writing articles the link is following:

http://site.com/sites/default/files/styles/large/public/field/image/my_i....

And he isn't being shown, and if I write the link of the picture down in the browser:

http://site.com/sites/default/files/styles/large/public/field/image/my_i....

Server nginx is giving mistake 404: 404 Not Found nginx/0.8.54. I configured nginx according to it: http://wiki.nginx.org/Drupal Perhaps somebody had similar probilem and does know how to fix it? I will still add that for the keying become integrated of editor wyswig tinymce. On lighttpd everything acted well but how I changed the www server on nginx then images don't just work

my real address is replacing sites with site.com

Can anyone suggest a Drupal friendly host in Canada? It should be on a shared hosting environment that also allows ssh access and the ability to use Drush. I know, that is a lot to ask... Dreamhost does this nicely, but their servers are in the USA, and this site has to be moved to a country that does not have a "Patriot Act".

Ive seen some comments about Godaddy hosting w drupal. I've had no problem with version 6 other than particular module challenges that come up. I found on the Godaddy forum that Drupal 7 may be a while so I'm going to attempt a manual install of 7.0. Here's the link to Godaddy's forum question about Drupal 7 availability.

I have a server:

Procesor Intel Bi Xeon E5504 8x 2.00+ GHz 2x4 MB L2 - QPI 2x4.8 GT/sec 45nm 64 bits
RAM 24 GB DDR3
HDD 2x 1500 GB - SATA2
RAID 0/1
GigaEthernet 1 Gbps

FreBSD 8.1 64 bit

MySQL 5.5.8
PHP 5.2.17
Apache/2.2.17 (FreeBSD) mod_ssl/2.2.17 OpenSSL/0.9.8n

The site is unique users 80.000 and page views 350.000

I do not know what was going on but after 10 minutes the server stops responding

Please help or advice on what to look for

My site just hit its 5000MB BandWidth limit, Im looking to raise it but not sure what a good number would be.
Simple questions so im looking for a simple answer. My website does not have users and is not a social networking site.

Thank you!
