Lumpy foundation

I purchase a home that is built on a slab with vinyl flooring. We would like to put hardwood down but the floor but it is really bumpy and uneven. What is the best way to even this out for the least amount of money. Sorry im new to this.

I have a simular situation, solid wood floors going down on slab. Mine has tile and sealer already down and is not even. I was told of two options:
1. floor leveler (a kind of thin mortar mix that self levels) then plywood and then hardwood

2. floor leveler then glue the hardwood down to that

A third option would be to use that thin plywood (cant remember the name, it's like luaw, luea something, it's hardwood and about 1/8" thick) use that to support the plywood under the low spots to raise them to level. this would take some time and a power hand planer would be used to get it as level as you can.

You can also rent a concrete grinder, it's a diamond blade grinding wheel on what looks like a small floor sander.

When you price the concrete leveler, it's about $30/bag at HD, but remember, you're doing a VERY thin coat, just enough to raise the low spots. Check if it's also a moisture barrier, wood doesn't go over concrete well unless you use a special glue.
I still haven't decided which way I'll go... but I'm leaning towards leveler + 3/4 plywood then nail down hardwood. Good Luck...
