I dont know where you live but in my area I got a guy in with a
construction hammer and trailer to remove an old set of front steps .
That was less than $100 for an hours work . The steps were only a few
inches thick but with dirt fill.

Then i got a kit for porch and steps . There were 6 posts to set into
the ground . The porch fastened to the posts, and the railings
fastened to the porch. the steps were about 12 x 2 cut at an angle and
there were cleats to support the stair treads, so the stairs could be
set at whatever height you needed.

Total cost for the kit was less than $500

In my experiance stairs should all be the same height for safety. If
the bottom step is very short (working top down with a standard riser
height) I would landscape a little and raise the ground level. Or
install a concrete pad two or three feet square so there is a little
step up to the pad , then a standard stairs to the porch .
