Eviction Notice and Court Filing Help Needed

I own a rental property in Texas and have a tenant who hasn't paid rent in three months. I've sent multiple notices but they're still refusing to leave or communicate. I need help preparing the proper eviction paperwork and filing it with the court. I also want to make sure I'm following all Texas landlord-tenant laws correctly so there are no issues. This is my first eviction and I want to do it right. I need someone to review my lease, draft the necessary notices, and help me understand the filing process and timeline. I'd prefer someone familiar with my county's court procedures.
