I have a deep and abiding respect for tallented artists who have refined their skills. The manual process of installation might best be left to dedicated installers.
Perhaps you overlooked my previous response.
"Of all the unknown area's of this trade, installation tops the list. I learned this lesson the hard way. So, no I don't do much installation. A client should be informed, up front, they will be hiring you to build a beautiful sign. You may want to include the installation price in your bid, but it should be stated, "Installation by Others".
