Add masternode to monero fork base

Am a leading coin developer, i seek more hands in my coin development. My cryptocurrency uses monero code base which suit my need for a masternode because of its privates transactions. All i need is to add a masternode to the code base. The amount to use in setting it up will be lock for like 4 month before the said amount can be used again that is if a masternode is setup, the fund for setting it up will stay for 4 months before it can be reused, in other words the fund will be locked for four months. The developer reward of 15% will be setup in the code base also. The cryptocurrency is currently trading and doing well so i would love to have contributors who will be developers. Thanks
