Dear Sir,
I have read your project description & checked both PDF documents carefully. I have found that this is a big project, as you want both Apps along with the back-end Admin, which means that WebServices (API) is also required. This is very much doable but not in US $1,500, as this budget is very low, in fat in this budget, its almost impossible to develop even single App.
So please initiate the chat to finalize the contract details, estimate, payment terms etc. but just so you know, I am flexible in prices, as quality comes first for me and then prices.
Look forward to hearing from you & start further discussion thru' private chat.
Regards,
YK
