Hi,
I have gone through the requirement and as per the understanding we need to do the following:
- Add subscription services to ubercart template.
- Create a theme which is accessible easily for desktop, tablets and mobiles. For this we need to create a responsive theme, which will work for all the platforms.
Just to let you know we have experience developers and designers who can work on the above requirement.
Please let me know if you have any query.
Regards
