PCB Schematic Electronic Circuit Design

I need a PCB layout for a PIR motion sensor activated LED strip. It is to powered using 3.3-4.2V 18650 batteries. I will need a suggestion for an easily sourced relay transistor and the supporting circuit for a low power and stable system. I would like to design for manufacture where possible utilizing SMD components when possible. Deliverable to be schematics and gerber files. BOM- (1)AS312 PIR Sensor Module (1)HT7530-1 3V Regulator (2) 2.00mm 2-pin JST connector (1)2.00mm 3-pin JST connector (1)Transistor Relay for switching LED power Any supporting capacitors, resistors, etc. as necessary
