Joomla! 3.x Template Creation Skype Training

I have a client whose in-house website guy needs training on creating custom Joomla template. This web person is intermediate level php/mysql/css/graphic design skilled. He knows his way around Joomla administration. However, creating custom template is something he needs help with. But he doesn't want it done for him. He needs to LEARN! If you can help, that'll be great. There's going to be around 2hr training session. And we'll need you to be on call for about a week after in case he comes across some questions that never were answered during the training. Or something that needs further elaboration. Remember, it's going to be around 3hrs of your time. Easy Money!
