Help. Looking for a CHEAP PCIE 2x M.2 NVME Raid controller

[JamesTheGreat]

Im in a funny spot.  I have a friend who own a mildly successful small business.  Most of his computer parts are my leftovers, which does him fine.  He runs 1 computer as its only him at this store.  I'm moving, so I'm trying to set him up in a way that he'll have a little more redundancy in the even of a failure and I'm 750miles away...
I want to swap out the 1tb Spinning HDD for an SSD (actually 2)

And I'd like to setup them in a RAID using a PCIE raid controller that supports 2 onboard m.2 NVME drives.  
Issue... I can't find a raid controller like that for under $400...

I'm good with one thats around $100-150... I don't need anything fancy, but it does need to be hardware raid, so if one drive dies, i can have him remove it and keep going.  Then he can install a new drive and itll rebuild the raid....
 

This is NOT a backup solution, but just a way to keep him up and running in the even of a Drive Failure.. (AND to speed it up since the spinning disk makes me want to jump off a cliff)

 

I'm not having much luck finding a cheap card.  If anyone knows of one, please let me know... I'm even open to using SATA raid if i have too. :(

why not just use software raid?

Replace with SATA SSDs ... he most likely doesn't need nvme speeds.

sata drives would be you best bet and at the lowest price.there is one card that i know of that dose traditional raid card that is from highpoint.

but they cost alot.

if its an amd system it might be supported by the motherboard and could achieve what your trying to do.
