You should try jump start then drive around to charge up the battery. I don't think it is dead, just ran out of juice since not used for 3 months.
Okay, through my experience for jump start.
May not be the starter also. Like mine is new starter but like you mentioned sometimes work, sometimes don't. Is due to old wiring or ignition switch, too much resistance. Adding the relay hooks up current direct from battery mah......lol

If battery is completely dead like yours, to do jump start you will need very thick cable. Sort of the 1000amp type that you will find in hypermarket.
Donor car must be started and let charge run for a while before cranking dead car.
If battery have power but not strong enough to crank, a 600amp cable might work. Forget those 200amp cable. Too thin to transfer the current....
Sometimes jump starting using cables might not work if the battery is really out of juice due to being idle for too long. What you need to do is just swap the battery (if you have another one), start the car then quickly swap the battery back while the car is still running. Then just leave it for some time or drive around to charge the old battery back.
If cable is with thin type then cannot. Got one time ex colleague called say car cannot start, so we drove to her house, to check it out. Turn key to crank got tak tak sound only. So she show us her jumper cable she has, then we hook to our donor car, but still cannot start. Told her maybe starter kaput, so we call our mechanic. He came took out his thick giant cable to jump start. Immediate loud crank and car started.
Yes, if emergency then just do like what I mentioned rather than keep looking around for thicker cables which still does not guarantee will work. So it's good if you know how to do swap batteries quickly while the engine is still running, then you don't depend on the cables as much.If cable is with thin type then cannot.

Our company audio show car, battery flat. It was completely flat as no tak sound even. Colleague took out his jumper cable to jump start got tak sound only. Then call me if I can help. I took my jumper cable add to his (double cable) and car started....
Your way sure can start, more work only......hhhahahhahah
My first intention was to inform if anyone is buying a jumper cable go for thick one. To get someone to loan the car to jump will be easier to ask whoever to remove his battery and loan to you to start the car.....hhahahhahahhaha
Yes but knowing how to do it fast is no harm either coz you might really need it one day. You may think the cable you buy is thick enough but if unlucky might still be not enough (the cable is thick just because of the insulator thick but not the inside!). Of course you remove the car battery yourself la, don't ask the other guy to remove it for you leh!My first intention was to inform if anyone is buying a jumper cable go for thick one.
