Fig leaf software is a credible alternative http://training.figleaf.com/Courses/sencha.cfm you can contact Arya Heidari [arya at figleaf dot com], they are very flexible in their training options.
Extjs is a nice framework for rapid front end development. However, There are a considerable amount of bugs in 4.0.7. Many of these are addressed in 4.1. I went from zero understanding of Extjs and javascript to being able to build a full powered web app in about 1.5 months. I am a single developer mind you, so I have to do backend/front end programming.
You only really need a basic understanding of javascript and css. The examples in the Extjs documentation are very good and that is how I was able to learn so quickly. The most challenging part of using Extjs for me was getting it to communicate with the backend.
where are you located? How many employees would attend the training? (What is your backend technology?) I have been giving two-day trainings (0.5 day Javascript, 0.5 day Ext JS, 1 day hands-on on Ext JS parts/widgets you most probably will be working with) before and would be happy to do the same for you!
To what are you referring with "there are just too many options available on the web"?
I'm right now located in Valencia, Venezuela (40 min away from Aruba, if you want to be very nice to your employees ;) or any other location would be fine with me.)

无花果叶软件是一个可靠的替代品 http://training.figleaf.com/Courses/sencha.cfm 您可以请联系 Arya Heidari [figleaf dot com 的arya]，他们的培训选择非常灵活。
另一个可靠的选择是 Jay Garcia 的公司 Modus。 他在 Action 中编写了 Ext-JS http://moduscreate.com/offerings/training/extjs/
就像我在另一个答案是，2000美元/人/周末并没有那么贵。 你得到你所付出的。

Like I commented in another answer, $2000/person/weekend is not so steep. You get what you pay for.

Extjs 是一个很好的快速前端开发框架。 然而，4.0.7 中存在大量错误。 其中许多问题在 4.1 中得到解决。 我从对 Extjs 和 javascript 零了解到能够在大约 1.5 个月内构建一个功能齐全的 Web 应用程序。 请注意，我是一名单身开发人员，所以我必须进行后端/前端编程。
您只需要对 javascript 和 css 有基本的了解。 Extjs 文档中的示例非常好，这就是我能够如此快速学习的原因。 对我来说，使用 Extjs 最具挑战性的部分是让它与后端进行通信。

你现在在哪里？ 有多少员工参加培训？ （你们的后端技术是什么？）
我之前已经进行过为期两天的培训（0.5 天 Javascript、0.5 天 Ext JS、1 天您最有可能会使用的 Ext JS 部件/小部件的实践），并且很乐意为您做同样的事情！
您所说的“网络上有太多可用的选项”指的是什么呢？
我现在位于委内瑞拉巴伦西亚（距离阿鲁巴 40 分钟路程，如果您想善待您的员工；）或任何其他位置对我来说都可以。）
干杯，
