Loose Bottom Step

We have a very olld 70s staircase. Unfortunately we took the bottom step off a few years go to check something out. Alas, we can't screw it back on properly. The hole the screw goes into obviously isnt cutting it anymore. The problem is there is not enough clearance to get a drill or screw driver under there to do it properly - Step to ground is about 13.5cm. Please can someone come and fix our step for us? All we need done is for it to be attached so that it doesn't wobble and come loose ( We will be renovating the steps in a year or so anyway) - All and any solutions accepted. If you think you can do it, please send me a quote. It would be great if it could be done between 30 Oct and 03 Nov.
