Hi there,
I have checked the link but this is a big project, would you like to provide some paid API for making calls within software?
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
