Iso someone to help make a prototype willing to pay $$

I am developing a pool cleaning product and need assitance from someone with an engineering background as well as pcb/audrino programming and cad design. I have made a rough prototype that gets the job done, but needs refinement to bring to production. Feel free to email me at [email protected] or call/text me for more info
thanks
