Welcome to BYC! This the best place I've ever found for sharing stories and getting answers for all your chicken questions. I'm glad you joined us!
If you really want a pre-built coop or chicken tractor, I'd look on FB marketplace,
ebay, or craigslist for someone selling their chicken tractor or portable coop. If you can't find one there, a "hoop coop" is probably the easiest coop in the world to build, and it's portable. Material list is short and skill level is about a "2".
I did a search on this site for hoop coops and came up with an abundance of threads and articles by different members, here:

Further, you could check out the Learning Center category for chicken coops for lots of great ideas and guidance, here:

I'd stay far away from prefab coops on the retail market. Seriously, do not buy one. They're notorious for being too cramped, poorly ventilated, and overpriced. As a suggestion for one who's "not very handy", you could hire a carpenter or handyman, neighbor, relative or friend to build one for you based on one of the designs above. It would be better built and cheaper than anything you find at a store.
FWIW, I once met a tiny little lady at a home improvement store where I worked. She said she "wasn't very handy" and had never even operated a cordless screwdriver, but she wanted to build her own custom shower in her basement bathroom. It took her a few years, but little by little, she built a 6-ft x 4-ft custom shower with bench and did all the carpentry, tile work, electrical (for a light in the shower), and plumbing all by herself. She watched videos, read instruction sheets, and asked bunches of questions. When done, it was watertight, fully operational, and absolutely beautiful.
So... don't be afraid to tackle a hoop coop by yourself. There's no "right" way to do it and you can't really mess it up. You just have to be creative sometimes to figure out a way to attach this or that and come up with ideas. This forum is a great place to ask those questions! Good luck!
