I have seen the example, where you can customize the watch but this kind of configurator cannot be done in US $750, as this is very low budget, so please let me know, if you are flexible in your budget.
I think one to one technical meeting is important to make sure that we are both on the same page in terms of requirement understanding, after that we can finalize everything to kick started.
So, please click on the chat button to schedule a meeting time, after that I can revise our bid.
Look forward to hearing from you.
