Yes, call a cement contractor and get a poured foundation.

If you prefer block then contact various masonary workers in your area. If you are in a fast growing area, plan ahead, since they can be very hard to schedule. This really is not work that you can do yourself. It is a skill that takes years to develop. I still marvel at how easy they make it look and how stupid I look when I try it. Good Luck with the new home.

I have to agree with Dr Home. It looks easy but is hard to master. I just finished laying glass block fo a bar. I'm glad it is not supporting my house!
Do hire a mason. Being out of plumb just a little can lead to many problems down the road.

As to my first post - why do you want a block foundation? Poured foundations are stonger and less likely to leak.
