I`m starting seeds here in Brazil and have exactly the same issues. My seedlings are on a card table in the front yard (they were supposed to be in the back yard, but recent wild weather made me bring them closer where I can protect them at night, we`ve been having freak hail). I rig up shade cloth that cuts about half the sun, kind of like what you might find in a garden center. Before I was able to buy it, I used some old gunny-sack kind of bags I had hanging around. In the past I`ve used sheer scarves tied up like a tent fly. It cuts the worst of the sun, otherwise you end up having to water 4 times a day.
I have found after a few years that the normal seed starting flats or egg cartons just arent deep enough, the seedlings just fry. i made my own sprouting boxes out of scrap wood, but I have also used whatever kind of container that has at least the depth of a shoe box. I`ve noticed a real difference in seedling survival.
