Dear Sir.
Thanks for your posting.
I'm very interested in your project.
Because, I have rich experiences in AR.
I already developed the several apps to use AR on iPhone.
I can send the demo videos of those if you want.
I'm sure that my these skill and experience are necessary for your project.
I attach the great importance to the requirements of clients, and so have done my best to provide the solid quality on time.
If you hire me, you'll realise about these in the first week too.
I would be happy to discuss about the project when is convenient for you and can work full time for you in your time zone.
You'll feel as though I work near you, even though we are apart from each other.
I would like to ask a few questions through the interview if you want.
Then, I think that the timeframe and budget of this project will be more specific and reasonable.
I look forward to hearing from you.
Sincerely
