Welcome, Sunrise....though I hope your interest in ECN goes beyond slipping in a 'free ad.' :-)
I would like to suggest an alternative to a bucket "truck.".....a towable trailer. I have used one - I think it was made by Genie- and found it most adequate.
Advantages I saw to the trailer design were (1) you only brought it when you needed it, and (2) unlike your truck, you can operate the thing inside a warehouse!
I have had good experiences with former utility company equipment, and found lots of atractive offerings at the auction site operated by the US Government ("General Services Administration.")
