how much to have someone install mobile joomle

I've put Mobile Joomla! on more than one website with no problem.
Then I hit this one. They are using "Multi-Site". Is this a problem? They are also using SEO links with the modified .htaccess. Is *this* a problem?
Here's the install log below (errors):

JFTP::login: Unable to login

Any help you could give would be very appreciated.

Joomla 5 Page Website
Traditional Site
No CMS Price
Range$300 to $500

In here, you will offer your client a traditional 5 Page Website, but you will hide Joomla.
What about if they found out you are using Joomla? Well there are ways to hide Joomla. Like disabling the Administrator Control Panel and eliminating the Joomla Generator Tag.
Also being honest from the start is another option. Just tell him that it is a Joomla Site.
However what I will recommend you in here is setting your prices from the beginning just in case he wants you to show him how to edit the site.
If he wants to take full control of the site without paying you for the training, make him sign something to make him responsible just in case he does something wrong while editing the Joomla Site.
