For me, searching something about electronics for half a day is not long at all. :-)
For example:
IRLML2502 - 4A/20V
IRLML0030 - 4A/30V
FDS6680 - 11.5A/30V
All N-channel, logical level input.
There's a ton of other good ones on the market.)
If you need something more powerful, maybe you should use some high power MOSFET. If it have higher switching voltage, use something for level conditioning like an additional logic level MOSFET.
