Dear Sir,
I have read your Project description & looked at the detailed word document attached by you. So, let me formally confirm you that our team is capable of do all the changes but can you provide me URL of your existing Application?
Please drop me a message thru' Freelancer PMB to discuss everything more in depth, as our current bid is not our actual bid but just a placeholder to submit the proposal & start our communication, because without entering any amount, we cannot submit the bid. Once you respond me, we can then discuss about the total cost, time-line & payment terms to move forward.
Look forward to hearing from you.
Regards,
YK
