Converting to Drupal

I'm looking for assistance porting a mature slashcode-based site (approx 20,000 users, 5000 stories, and LOTS of comments) to Drupal. If anyone has any experience, I'd love to hear about it. If anyone is interested in doing the work, I'd love to hear ballpark figures about cost.

Also, I'd like some idea of how well Drupal scales to meet 75,000-100,000 page views/day. I know there are some (much) bigger sites using Drupal, but with only one server available for webserving and database duties, is it possible to get good performance at those numbers?

I have an existing website design, xona.com/new, that I wish to convert into Drupal. Is there existing information that shows me how to do precisely that?

The website will be nothing more than articles with screenshots. No commenting, no logins, no sessions IDs in the URLs, no fancy URLs. I want my URLs to remain simple, such as xona.com/pong or xona.com/breakout, for examples. (Not having simple URLs is a deal breaker for me, but I have been informed it is possible with Drupal.)

Your opinion... Is Drupal right for me?

I have been using ColdFusion to develope my business and my clients sites. My site, www.tecito.com, is using coldFusion.

Hello,

I never try drupal before but I've heard it is good for blog, forums, custom php and new-makeover look. Not like vbulletin that you can recognise their style. For drupal forum, you can make 'un-drupal' look. Is it possible?

I'm not going to use drupal for blog, only forum. I just want to know if its possible to make 'un-drupal' look.

** Forum site **
Having CSS style look, two columns (100% width page)
Not default drupal CMS look

Okay next problem

I have setup a page I want to use as a web portal for my users. Now I have customers for browsing the site and I have return customers that I'd like to be able to setup a portal for.

So far I have created a new page and linked a subdomain http://customer.xyzcompany.com
So when we setup new computers they will go to the portal page while my other customers only see the www.xyzcompany.com
