Hello Friend,
I am the topmost freelancer in Opencart skill over freelancer.com, you can check our reviews/portfolio for our experience. You can check my reviews for my experience and trust. I can develop same functionality you required.
I have few questions:-
1) As you have mentioned that the form we can select to show on particular product on tick of any field, So my question is that is it based on customers, like the form will shown only 1 time and after we received the data we dont need to show the form again to that customer?
2) For which opencart version we have to develop this functionality?
3) What will be the dead line?
Please respond my questions and let me know if you wanna ask me any question regarding this.
Looking forward for your valuable response.
Kind Regards,
Pankaj Modi
