Need urgent repair for leaking kitchen pipe

Hi, I have a persistent leak under my kitchen sink that needs fixing as soon as possible. The water is dripping steadily and causing some damage to the cabinet below. I would prefer someone experienced with plumbing repairs who can identify the source of the leak and fix it properly. Ideally, I need this done within the next few days. Please bring your own tools and materials if possible. Looking forward to getting this sorted quickly.
