Hello,
I was recommended your project and would like to discuss with you. I just want to be realistic about the job, but I would be willing to try to get what you need.
I think that it is difficult to guarantee this project can be completed as you describe. YOu should also know that all Apotheke in German are independent small businesses - there are no chains. I believe it is forbidden by law. This means that they are small and with very vigilant staff. The chains here are "drug stores" - like DM and Rossman - they do not need a pharmacist to be run.
I do understand what you are asking, of course and can locate Apotheke for you. Success, even with a mobile phone could be a bit hit and miss. You obviously understand this to some extent as you have said as much in your document attached.
I look forward to discussing further.
Thanks,
Nikaya
