Looking to 'flip' existing internal staircase to go the other way

We have an internal L shaped staircase (8 steps down, a square landing, then 2 more steps to the ground) that we wish to flip the other way on existing walls and footprint (probably corner steps to get around 180 degree turn then straight down to floor). The bottom part of the staircase is currently being striped away due to flood remediation so we thought this would be an opportune time to find out what the costs are to change direction before putting back rather than having to do all that work again later. Depending on costs, would consider paying for full job to be done vs paying for staircase to be built then we install ourselves with builder help. Note - strip out and cleaning works still on going so would not expected to have site to view until later half of next week. Thanks in advance
