Dear Sir,
I have read your project description & checked the attached PDF document to understood the overall features/modules requirements, which is nicely explained. Let me formally confirm you that we can deliver this website successfully but there is definitely a difference in our estimate and your selected budget of AUD 3,000 because of the overall features/functionality.
I also have couple of questions to ask but due to character limitation here, I can ask questions once you drop me a message thru' chat.
Please initiate the one to one chat to discuss more in depth, so I can give you my high level understanding to make sure that we are both on the same page, I can then also revise our bid.
Look forward to hearing from you.
Regards,
YK
