Greetings,
I have read Project Description & understand that you want iOS & Android App for Trading system but then you would also require WebServices for the communication, which means that our estimate would be higher than your set budget. However, please provide me detailed requirements, some high level features/tasks or reference/similar example App, after that I would be able to give you an accurate estimate in terms of time & cost.
At the moment, my bid is just a placeholder, as I cannot submit the proposal without entering any amount but once you respond us, we can then finalize the estimate.
Look forward to hearing from you.
Regards,
YK
