Need alterations tailoring for a dress and suit hem adjustments

I'm looking for a skilled tailor to perform some alterations at home. I have a formal dress that needs hemming and minor taking-in at the waist, plus a suit jacket sleeve adjustment. Ideally the tailor can come to my home in the afternoon, bring sewing tools, and work with standard UK sizes. Please confirm fabric type, whether alterations can be done without removing buttons, and provide an approximate turnaround time. I prefer eco-friendly threads and a clean, precise finish. If you have experience with delicate fabrics like silk or satin, that would be a plus.
