Technical Sourcing Interpreter — Shenzhen factory visits (telecom/RF), 5 days + pre-trip research

I'm the CEO of a West African internet service provider visiting Shenzhen (Nanshan, Bao'an, Longgang, Pingshan districts) to meet 5–6 manufacturers of LTE/5G outdoor CPE equipment, plus possibly an antenna factory in Dongguan/Zhongshan. I need a Mandarin–English interpreter with electronics/telecom sourcing experience. Scope — two phases: Phase 1 (remote, before the trip): verify 6 companies' business licenses and manufacturing scope on Qichacha/Tianyancha (company list shared after hiring), confirm the meeting schedule with each supplier, plan daily routes. Phase 2 (on-site, 5 days): consecutive interpretation during factory tours and technical/commercial negotiations (LTE bands, antennas, firmware, MOQ, tooling, QC/RMA terms), note-taking, cultural guidance. Requirements: proven factory-visit/sourcing experience (references or reviews), comfort with RF/telecom vocabulary, own transport knowledge of Shenzhen industrial districts, and a signed declaration that you accept no commissions, referral fees or gifts from any supplier — compensation is your fee from me only. Dates: flexible, targeting early August 2026. Please quote: (a) Phase 1 fixed fee, (b) daily rate for Phase 2, and briefly describe a past sourcing visit you supported.
