There are guys that deliver it by the truckload. Talk to a nursery where they are growing plants, not just selling, and they should be able to give you a name and phone number because they buy it. Good topsoil is very very hard to find and you should see a sample before ordering. You would be lucky to find some and will probably have to mix the available dirt with compost, rice hull, dolomite, manure .... to get something decent.

Don't know prices as have not bought in a long while.

I am not in Chiangmai, but still,have never even seen "real" topsoil for sale. Before I started building my house, I raised that land a little with fill. I am not thankful I had the presence of mind to have scraped off the top 8" of topsoil and stock piled it in back. It is great, blackish loam that falls apart in your hands. Beautiful stuff.

Most people fill their land with a bunch of dead rice patty clay, then nothing grows on it.

A suggestion is to ask around to find anybody starting work on a project where they do not need the topsoil (like a commercial project), then ask for it and agree to pay a premium. If you do, though, you MUST micromanage the collection of the topsoil, or they will go too deep and get the crappy stuff.

MaeJo, 350 cubic metre, delivered. Go through MaeJo and turn right on the Mae Rim road, on the left after one kilo. Decent quality top soil or soil sand mix.

 I agree with the above..., If your topsoil and manure is for growing food (fruit, nuts and/or vegetables), be especially weary of un-composted manures (in any form - especially chicken manure as it's the highest in Nitrogen manure) touching stems, trunks and/or foliage..., for safe food production manures ideally should be composted(aged) and mixed with some carbon/fibre based material. If you can', buy or make some bio-char (Bio-char is basically crushed up hard wood charcoal - or simple carbon), to add to the mix. Bio-char and rock mineral(Dolomite) both hold on to and later slowly deliver available nutrients..., those nutrients are especially made 'more available' to plant roots for uptake if microbial activity is encouraged with composting. Little or no added or available Bio-char and rock mineral(dolomite) can allow any 'delivered nutrients' to be washed deeper down and eventually into the water table. Ideally aged manure, vegetable mater compost, bio-char and rock dust mineral (dolomite) all mixed in together - if you can. If there is clay in your finished product.., a little gypsum(thoroughly mixed through) can also help break up 'clumped' clay and allow any 'nutrient laden' water to penetrate to deeper roots rather than pooling on the surface. Also, just a 'little' potassium sulphate(basically potash) can be later mixed in on the surface - while the plants are growing greenery.., but before they grow to produce flower, and then fruit (without disturbing any plant roots) can help with fruiting and flowering of those plants later. 
Please excuse my overly long rant..., I may well be off track...., whatever, I hope it helps in some small way.
