Honestly, unless you can bring in a lot (as in like at least 3 - 5,000 people a day) of traffic and a lot of advertisement revenue, faucet sites just are not very profitable anymore. Back in the day when BTC was only like $5 or $10 a piece, it was way easier and cheaper to start up, since you could give away larger amounts of BTC without it being expensive and the standard transaction fee was only worth about half a cent. There also never used to be the transaction "dust" limit (you cant really send any transactions that are less than 0.0000055 BTC).
Ever since BTC has been $100 - $500+ each, it now is way more expensive and difficult to run a faucet. Not to mention there is sooo many of them already. You are probably better off investing the time into creating a different service
