W5500 Ethernet integration

I am building a small sensor node and a Wifi receiver base module. The sensor node has 2 temperature sensors (DS18B20 1 wire) and a water leakage detector (ON / OFF pin). Both circuits use a PIC16F1513. The temperature data is sent wirelessly from the sensor node to the base module. We use a Wireless Transmitter module RFM95W 868 MHz (using SPI communication). The base module will send the data to our distant server using TCP/IP using a Wifi connection : ESP12-E module (ESP8266 Wifi Module) (using uart and SPI communication). We already have the pcb and a first working embedded program (node and base). We want to add a W5500 Ethernet communication to the base using an existing W5500 pcb module. We have a first working version of the embedded program with the Wifi communication. This code need to be tested and eventually modified. You need to develop and test the code concerning the W5500 Ethernet communication : TCP/IP client that gets a dunamic IP address using DHCP protocol and sends data (5 to 10 bytes long) to distant server using TCP/IP. We can provide you with DHCP and W5500 library examples. The server side code has already been done and tested. We can provide you with the testing plan and scenarios. We are interested in a long partnership because we need future new developments to be made on the ESP12-E (develop a new LUA embedded program). The embedded software must be written for MikroC for PIC from MikroElektronika or MPLAB from Microchip and must be well documented. We will send you a node and a base module with all the necessary parts (ds18b20 temperature sensors …).
