Hi there,
I have read Project Description & it seems pretty complex plugin, which definitely requires experienced Wordpress plugin developers, so I am thinking to assign 2 dedicated developers along with one team lead, because design wise, there is not much work. 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.
I can show you some of our past work on your request, as most of the clients don't like that we post Application URL's in this initial bid post.
Look forward to hearing from you.
Regards,
YK
