Nice to meet you.
I'm one of the Product managers for [url removed, login to view] and we are looking for talented designers such as yourself to help design our new Android app and wondered if you would be interested?
I understand you helped design our new timetracker app and would love to hire you for more work.
Looking at your online profile you seem to have a great eye for design and
experience designing android apps and would be a great fit for what we need.
To start with I would ask you to just try design just one screen for us to see what your design style is like.
If successful we would then pay you for ongoing work to design the rest of the app (which is about 10 screens).
Let me know if interested, thanks
