Custom ESP32 IoT Device Development

I'm in need of an experienced developer to create a few small, custom ESP32 projects for me. The project involves building IoT devices with the following essential functionalities: - WiFi connectivity: This is crucial for the device to connect and communicate within a network. - Sensor integration: The device should be able to integrate with various sensors for data collection and processing. - Storage: The device needs to have a storage solution for data logging and retrieval. - Speaker: This will allow the device to produce sound. - GPS: The device should be able to track its location. Ideal candidates for this project would be those with a strong background in IoT device development, particularly with the ESP32. Experience with sensor integration, data storage solutions, and audio components will be a significant advantage. Please include relevant samples of previous work in your bid. I want someone to make prototype unit and send me schematic/gerber/firmware for these. I feel each project can be completed in 1 week period with lot of online repository. I want these to be tested first so for me assembly of same is quicker. I have budget of around 5000 INR for each of these and have around 40 ideas of different project and i can do each one on weekly basis. The 1st 3 idea are 1. web usb drive using esp32 ..means it work as USBdrive and we can change content on Wifi using url 2. wifi speaker unit which take content on url and play audio 3. esp32 walkie talkie unit with alert flasher where a remote site can send alert on TCP and the unit can communicate to other similar unit and talk like a walkie talkie Please post bid for one project and timeline for the same. The cost of components for each project will be separate and i will pay for the same. I will pay for shipping of prototype unit to me also. I will select 2-3 vendor so we can do more project at same time.
