Being that your interest in options is to protect gains until 7/18 (when you've held the stock for 12 months), I'm going to advise you contact a tax expert. While I'm no tax expert (so this info may not be correct), but I believe that if you purchase a put option to protect your losses that the time you hold the put option would not count towards the 12 month capital gains holding period. As such, you have roughly 5 months remaining -- if you purchase an option that expires in 5 months, then come 7/18 you will still have 5 months remaining for it to be taxed at capital gains rate.
In short, you only get the capital gains rate if your investment is at risk for 12 months. The time you hold the put option means your investment is no longer at risk and that time doesn't count. So you held for 7 months, if you buy and hold a put for say 3 months, you would then need a total of 15 months holding the underlying to get the capital gains rate (7 months at risk, 3 months not at risk, 5 months at risk again).
Again, I'm no tax expert and the nature of my trading has no concern for capital gains rate, but I think that you should investigate this more thoroughly before making the assumption that a put is appropriate and find out far too late (after you've sold in 7/18) that you actually got the regular income rate rather than capital gains.
