Fully upgraded Creality CR-10 S5 firmware -- 2

I bought a Creality CR-10 S5 and fully upgraded it and changed a few things and now I can’t find firmware for my new configuration. I tried visual studio code and arduino ide using marlin and klipper and I’m having trouble figuring it out so I need to hire someone to do it for me in a way I can upload it with my slicer software. The body of my 3D printer is all original Creality CR-10 S5 which is the biggest I could find which has a 500 mm by 500 mm by 500 mm build volume. I put in Big Tree Tech SKR mini E3 V3 mainboard, Micro Swiss direct drive feeding, Dragon fly hot end with cartridge style thermistor like e3d that can read temperatures over 500 Celsius with 12 volt 70 watt heating cartridge to get over 500 Celsius temperatures and upgraded hotbed to get up to 180 Celsius. I upgraded my 3D printer so I can 3D print in all filaments on market and even make my own by recycling plastics, polymers and rubber. I need marlin firmware to run my configuration and have no temperature limits and no size limits but if it has to have limits then I want it set up to highest limits I can get, I also want thermo runaway protection in firmware and has filament runout sensor. Please send me a quote on how much you charge and hopefully get started because I can’t wait to go 3D printing crazy with all my different types of filaments I have?
