Developer training and support required

I'm looking for an experienced Drupal developer to provide training and/or support to an established web development team looking to get up to speed on Drupal quickly. Support estimated to be 2-3 months.

The existing skill set covers Linux sysadmins, XHTML/CSS, PHP, JS, MySQL etc but no Drupal experience. 

Options:

1) Training (onsite or at your location)
2) Telephone/IM support for technical/how-to questions that are obvious when you know the answer
3) A combination
4) Other suggestions welcome

The idea is to avoid some of the common mistakes and get up to speed quick on the more complicated theme and module issues. Option 2 is probably most appropriate but I'm interested in other ideas. Please include an idea of your costs relevant to your suggestion.
