Guitar strap nail completely stripped guitar...?

I have an Ibanez RGD321, with strap locks. At a recent band practice, the nail had become slightly lose, and having strap locks, the nail came out before anything happened to the actual strap, leaving a huge chip near where the hole should be for the nail. So, I can't put the nail back into the guitar, because of the chip. I went to my local Guitar Center, and the guitar repair man said that he couldn't fix it because of insurance/financial things, I can't remember, but he said to fill the chip with epoxy with the nail so it would form to the nail. I also asked a friend that plays guitar and he said to get small pieces of toothpicks to fill the whole, and put wood glue on it. My friends dad had recommended a longer nail, and then said to get a longer nail *and* use epoxy. My mom had said that a longer screw could potentially split the wood.

I'm not looking for the most cosmetically appealing approach, just one that is most secure. I don't have the time nor the money to get it fixed somewhere professional, and I have a show in one week. Also, I know that whatever way I try to fix it, it won't be as secure as it was, but I won't be handling it as hard (i.e, crazy stage presence) but someone please help me out.

Thanks.
