starlight Hi
1) To be 100% certain, It is quite necessary to see specific search module in live or production site as the specific module is 3rd party paid extension. Could provide the necessary guidance thereon 🙂
You can provide us with the link to specific site or admin details, if needed, as the module has been assigned to the particular position.
If unable to assign the specific module nor create the needed module position, We can try to help further with it 🙂
2) The payments team can confirm about the same as it depends upon the magnitude of the work required although JA do provide custom services for members as outlined here
Hope the information helps
Cheers
