upgrade existing project of voice listening - part 2 for completion

This is the part 2 of previous project that i have awarded to developer super2lao . The software was not completed. but tested successfully. i need below tasks now: 1-: complete the software and build a single exe version. 2-: fix LAN issue and make it working on lan. either UDP but TCP preferred. 3-: Lower voice delay as much as possible . current voice delay is 3 to 5 seconds. remove IP option from clientinstaller . because there is already IP option in server app for LAN and Internet users. 4-: remove Listen and Record option. instead make both listen and record option togather. so when someone click on "PLAY" , it play sound directly and also record sound at the same time. after that we have option to either Save that file or discard. So instead of record and listen we have a new option "Play/Stop" audio and "Save/Discard" recorded audio file. 5-: make 500 trial codes in this server software and give me those trial codes. each trial code will expire after 1 month and ask for full version code. if full version code entered then software will continue. otherwise will not work and continue asking for full version code. Send client to this link to buy full version code: [login to view URL] 6-: make 100 full version codes in server software which will never expire. 7-: do not put any of your email, contact details anywhere in my software. Price: $200 USD as agreed.
