What is the correct process for applying for a 90-day Non-B visa at the Thai consulate in Savannakhet?

Hi. Just wanted to verify.

I am going to Savannakhet to apply for a new 90-day Non-B visa for work. I have the appropriate paperwork from my new place of employment.

I believe that I no longer need to make an appointment through this website: [members only]/

The process should simply be.

1) Prepare paperwork. Upload as much as I can into the E-visa website: [members only]/

2) Enter Laos

3) Between 09:00 and 10:00 upload additional verification that I am physically in Laos. This can be a photo of my Laos entry visa.

4) Pay the Visa fee. I believe that I must do this in-person with cash at the Thai consulate in Savannakhet.

5) Wait for the visa to be emailed to me. Or will I go to the consulate to pick up the visa after being notified?

Is this correct? Anything I am missing?
