Your choices aren't very good. They seem to overlap. Also, when doing a wrap, I don't see how anyone could do a professional job outside, unless you're talking a partial wrap and you only have a few hours in it.
In colder climates working with torches and trying to get vinyl to stretch around numerous areas.... how could you possibly tell yourself, you're doing a good job while it's snowing on you ?? How do you keep plain dust and insects off the vehicles ??
It would be better to have your poll with inside at your place or on site inside their place.
If they don't bring it to you.... how is it gonna get to you to do in the first place ??
If you don't have the proper equipment and bays... you shouldn't be wrapping anything without an agreement with someone with an adequate well-lit heated bay.
