Hi L.,
Cloth diapering has evolved over the past few years and there are so many options available to you. We cloth diaper our 22 month old son exclusively, and I operate a store that sells diapering products as well.
The most basic changes you can make include replacing pins with snappis. They are only a couple dollars, and you only need 3-4. Plus, ditch the non-breathable vinyl pants and get 3-5 great diaper wraps like Thirsties.

Beyond that, you can switch from prefolds to fitted diapers (which still need a cover but are shaped to fit baby and have snaps or velcro at the waist and elastic at the legs to contain leaks.
Or you can invest in pocket diapers or AIO diapers that have a waterproof outer (so you don't need a separate cover), elastic legs and snap or velcro waist. Aside from the stuffing of the pockets when you do laundry, these diapers are just as easy as using disposable diapers. No covers. No pins.
You didn't mention how old your kids were or their weights, but you can also look at One Size diapers. They are as easy as pocket and AIO diapers but adjust from small to medium to large. Great cost savings, for such an easy diaper.
Please let me know if you have any specific questions. Happy to help. We've sampled dozens of cloth diaper brands for our little guy!
