Hi there,
I have read Project Description & understand that you want to build a large listing website, so let's get in touch and discuss the overall scope of work, because such project can be done by some team like us, not any individual developer. So, please drop me a message thru' PMB to start further discussion because I cannot write much on this initial message bard due to characters limitation.
At the moment, my current bid is just a ballpark estimate but once you respond me, we can then negotiate it & finalize everything, as I am flexible in prices.
Look forward to hearing from you.
Regards,
YK
