That looks like a great shed.
Moving a shed- easy if you know someone with a skid steer and a big enough trailer. Otherwise I have no idea. Since that's a ridiculous (and by that I mean ridiculously low) price for a shed that size, it may be worthwhile to rent a skid steer if you don't know someone who has one. Or if you know 6 or 8 strong people you may be able to screw on handles and lift it onto a trailer. I should stop talking now, I've never actually done this before...
But the real reason I'm posting is to encourage you to get moving! I was like you before- anxious and overwhelmed about whether or not I could do any of the stuff involved in building a chicken setup. I don't know anything about construction either, and am not terribly strong. I didn't build a coop on my own or anything, but I did fix up a shed including adding ventilation, a pop door, and a brooder (on a shelf in the coop), and I completely built the run by myself, including 4x4 landscaping timbers sunk 3.5 feet into the ground. I would say stop worrying about your physical limitations (mostly). Tools and things exist in almost all cases to help weaklings like us

I used a walk behind skid steer with a post hole digger on the front to dig the post holes (hard to get used to steering it, but otherwise easy peasey) that I rented for a half day.
However I do understand the financial limitations- between renting the post hole digger, the fence posts, and the fencing and other supplies the run alone (about 30x30) cost about $400. That's a lot. But I was kind of obsessive about it being super strong and lasting a long time, and about being able to walk into it without crouching.
So far as money, do what you can afford and what feels right to you, but stop worrying about it and start doing it- I know from experience that "doing" will make you feel so much better!
