Unless you live in GP a property manager is the way to go.
He is in default of rent and have likely violated a number of clauses in your agreement, so either you or your property manager must go and serve 2 weeks notice, preferrably in person. I think taping a letter to their door is okay too.
Once you've done that, go through the steps shown here:

Here are the first set of forms you will need to fill out. Make sure you attach and label all your evidence as noted. Go to the local courthouse, pay the $75 filing fee (which you can claim in the form as well), and they'll set a court date for you sometime after your 2 weeks notice. Note: Can't claim late fees. You can try, but the judge will just throw those out.

The courthouse will have you serve the papers to the tenant. I think you have 3 tries to give it to them in person prior to the court date before you're allowed to just tape it to the door. Either way there's a minimum number of attempts. So if you don't live in GP, someone will have to do it for you.
On the court date, let them know that you've properly served them. You'll then meet with a judge. The judge should rule in your favour, especially if the guy doesn't show up. Are there kids living in the home? That might make it a bit harder. Decide what you want to do with the tenant. If you just want them to catch up on rent, you can have a payment plan court ordered. If they miss a payment as noted in the order, you then have the right to call a bailiff and evict them. Or if you just want them out and evicted right away, you can do that too.
Either way, if you want them out or if they're in breach of the payment plan, you can serve them eviction notice. 48 hours and then you can call a bailiff.
Just went through this recently. But for me my tenant was just late on rent, so I just forced her into a payment plan, of which she's been complying. The second I think she's screwing me over, I'm within my right to evict her immediately. I nipped this in the bud early on. She was only a month behind, but the longer you let these things go, the worse they tend to get.
