Custom XLR Cable Soldering

I need several microphone-grade XLR cables professionally soldered. Each cable will be XLR-to-XLR, so please prep both male and female XLR connectors, tin the conductors, and finish with clean heat-shrink for strain relief. Although most of my rig also runs TS & TRS lines, this specific batch is strictly XLR on both ends. All joints must be shiny, mechanically sound, and noiseless when tested with a continuity meter and an audio sweep. Please return the finished cables fully tested and coiled, ready for studio use. Let me know how many you can turn around in a single run and the expected timeframe so I can ship the raw cable and connectors to you right away.
