When it's warm I feed outside in bowls. If I feed in the house I just lay a dog towel down and let that have it. They are trained to stay on the towel.
I don't ground the ingredients, but I do keep ground patties in stock for when we go traveling or friends dog sit.
It will be difficult to feed raw without a freezer. By difficult I mean more expensive. It's a personal thing you have to decide of it works for you, it seems you're a little backed into a corner at this point with the kibble.
It depends where you live, some areas have great local companies that provide ground raw for a good price. Just make sure you know what is going in it, and in what amounts. You can choose to do ground patties, they are easy to fit into a fridge/freezer. Supplement with a few raw bones for teeth health, like turkey necks.
Good luck on your quest!
