Greetings,
I have read initial high level requirements & understand that you want design/layout of your facebook App, so may I ask you to please provide me examples or requirements of your design project.
We have 3 senior Designers, so we can surely come up with few mock-up design options but how many total screens you want us to design?
We can also take care of HTML/CSS and further development, as we have 50+ developers, few designers and some other staff in house, so any kind of development is not a problem.
Please let me know, if you want to review some of our past work as I don't want to bombard you with lot of links at first place.
Look forward to hearing from you and talking to you further thru' Freelancer message board.
Regards,
YK
