Profile and Piles

We are getting a 8m x 4m tiny home/sleepout put on our back yard. Need profile done and 8x piles I guess. Been trying to do most of the work myself but if I get this part wrong the rest is **c$ed. Unsure if just doing 125's wood piles is best or different footings would be better. Ive excavated the ground where the sleep out is to go. and know when Im not skilled enough for the next part. I fully know foundations for a 8m x 4m isn't the biggest job in the world, or if one of you builders is like " We will do profile" and give you some advice so I'll have to dig the holes etc The home/sleep out is being built over the xmas new year period as some of the workers at the business wanted to work over that period and not take time off, so was happy to assist them. I guess No work = No pay
