Greetings,
I have read Project Description & seen all the attached images to understand the overall scope of work. Honestly, this is a big project, as it requires at least 3 dedicated developer's team, one senior team lead, who will manage this project along with designer and testing developer. Let me know, if you want me to give you our high level understanding/approach to make sure that we are both on the same page but please drop me a message thru' PMB to start further discussion about your project, as we cannot write much on this initial message bard due to limitation of characters.
Our current bid is just a ballpark estimate but once you respond us, we can then negotiate it & finalize, as we are flexible in prices.
