Base faucet should be quite easy technically (just send some money to the wallet and then put up a form to disperse them).
But you should at least some anti-abuse measures (compination of sending only limited amount of times per ip per time interval, captcha, ...), otherwise bots may suck the faucet dry in mere minutes.

Perhaps logging to show how much was sent from the faucet may come in handy, to keep ledger with the funds. Once the amounts are low, you may also need to group the transactions o save on txfees.

I'm quite busy currently due to project deadline, but perhaps I'll whip up something useful next week.
