Is there any way I can get into contact with the people over at WordPress? Either by contact form, email or phone?
Not really, and they are a tad steep in price -- if you are looking for installation support/consultation.
If you need help that you are willing to pay for than your best bet is to leave an email address here as a way for ppl to contact you.
The thread will then be locked to avoid bidding wars.
You can also post to the WP-Pro mailing list @ http://lists.automattic.com/mailman/listinfo/wp-pro
If that's not enough, there is even this:
Mind you just about any old timer here can install wordpress in 5 minutes unless there are server issues, which isnt often the case.
