Build A Simple Crypto Coin for me, can be a Hardfork

I need a bitcoin hardfork developed and set up as a mineable coin. Everything else will be exactly the same as the original bitcoin but larger blocks and it will be forked at a block just before segwit. Need it all set up and tested with Linux, windows and Mac wallets. It can be a Zcash hardfork as well so it need to be Bitcoin or Zcash, I mean we will decide it with the discussion. You are responisable for hosting nodes and everything. We will create depostery on our own name on Github as it's going to be a opensource project.
