Replying to What camera setup to use for full time/commercial use?

So there's a possibility that I may get a photo/video production job for a local tourism bureau and from what I know atm is that I would use my own gear.

I have a Canon T5i with kit lenses and a 50mm. I can get nice photos and video but I'm not sure how great it will end up being for full time photography and video use.

So, with your guys experience, is it worth upgrading to full frame, L glass and the works? Or could I get by with just upgrading my lenses?

If I should upgrade across the board, what setups have you used that work well on a commercial basis?

Just upgrade lens, what higher end lenses work well with a crop sensor to get a wide range of photos?

Thanks for any help!
