Hi,
Hope you are doing great !
To begin with, here are couple of point that I wish to clarify:-
1) What third party system do you wish to integrate ?
2) What will be the user flow?
3) Do you have any other reference ?
Kindly provide the project specification, so that we can have clear understanding of the project and can take things forward from there.
We have mentioned a ball park estimate at the moment, once have the details will provide you with the exact quote.
*Rest assured Time & price will not be a deal breaking factor between us.
We can start off as soon as we are being awarded the task.
Anticipating your positive response.
Regards,
WPOPPO
