@Joe Splitrock @Theresa Harris thanks for responding.from my understanding there are those portable machines that do not require hook up. and i would obviously charge a fee as mentioned in post

You have a depot in the larger town where they take their items to portable storage units and then you haul to your storage location.Why would they go to small town USA 20 miles away?   

Paper currency got its start as little promissory notes to pay gold, and then because the notes were more portable than gold, people started using the notes as money instead of the gold itself, which is why you sometimes see references to "one dollar notes", etc.A seller may or may not accept a promissory note as payment. 

They have portable A/C there.

It’ll serve two purposes-income and a getaway for my family I have a very portable job if I need to stay in the local area to get everything set up 

There are some portable cleaners that heat to higher temperatures, but they often come with two power cords, because they need two power circuits to reach the high temperature and provide suction.  2.

Also, title examining skill isn't portable. 

If it is truly hot and requires A/C, I would purchase a portable A/C unit on Amazon.com and when they are done with it, use it when you need it in other units. 

A laptop may be preferred due to portability but if there are suggestions of desktops I will look into them. 

Offer to get a Portable Storage Unit that you pay for 30 days and have them get it back from her?
