That would not be hard to do in Hardwood I do these all the time . If you want you can PM me and i can walk you through it . The treads (the part that you step on ) run about $25 each and the Risers ( the part your toe kicks ) depends on if you want paint grade or stain grade . . You will need a table saw and a slideing chop saw . Like i said send me a PM and i can give you detailed instructions on how to do this .
