Relocating from Dallas to Austin

I am moving from Dallas to Austin next month and I am stressing about the logistics. I have a 3 bedroom house with a lot of furniture. Traditional moving companies are quoting me 3k to 4k. I have been looking at IMS Relocation because they are based in Dallas. They also offer portable storage containers which seems more flexible and cheaper than full service movers.

Has anyone used them for a move in Texas. How was the pricing and did they deliver on time. I am trying to decide between hiring a full crew or loading a container myself
