Hello,
I have famialiarized with your requirements and decided to place a bid. I am confident we are able to make your application work perfectly from both: technical and aestetic point of view. However, I need to know more details in order to properly estimate the project's complexity.
I am happy to discuss this project in details with you. Should you have any questions, please do not hesitate to contact me. Thank you.
Best regards,
Jacek Francuz
