Dear Sir/Madam,
Thanks for inviting us. We have extensive experience in Mac OS development, since OS 9. I have >10 years if experience in Pascal and Objective C development. Also, our members are teachers of Design and implementation of operating systems at local universities, so we are familiar with the quirks of the os. We have also developed several device drivers and apps for Mac OS X.
We would like to know more about your project to adjust our quotation.
Thanks for reading and regards
