Greetings,
I have read Project Description & we have 50+ developers, few designers and some other staff, so our team have multiple skills/expertise, but we really need detailed requirements, some high level features/tasks or reference/example websites, after that I can confirm you our precise estimate.
Our current bid is just a placeholder since Freelancer requires to submit the proposal but once you respond us, we can then finalize it.
Please check out our Freelancer profile https://www.freelancer.com/u/leadconcept.html, as we have delivered many successfully projects lately and let me know, if you want to see some of our recently developed projects.
Look forward to hearing from you.
Regards,
YK
