Greetings,
I have read high level requirement but do you have more detailed specs for us to estimate it?
Of course, we do have all the expertise/skills mentioned by you in the Project Description.
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
