Aside from hiring a moving company (you're kidding right?) the other two ideas work. The do-it-yourself option is of course the best; the heat? part of the business, as is the cold, the wind, the dead mice, the trips to the dump, the cleaning of the items, the sale of the items. That's what this business is about (on the negative side).
On the positive side you mind find it fun to go on a treasure hunt in a locker you bought; to make money on sales, to get stuff for your own use, etc etc.
The alternative is some regular 9 to 5 job which is more guaranteed to keep you out of the heat (unless you're a construction worker or a gardener) and to give you a regular paycheck and medical benefits. Only you can decide what works for you. Try it out. If you don't like it in 3 months to a year, quit.
