Add/Invite 40K contact list to my Telegram Channel

I have 40K mobile contact numbers in Txt format and would love to add/invite them to my channel in Telegram Mobile Application ( see more here [login to view URL] ) . I will pay only when at least 50% of them become my channel's member. All mobile numbers are from Iran and starting with +98 . The project has 3 phases, if we get a good results from first phase in next phase we want to add 80K contact numbers and 120K in last phase. All depend on your performance.
