ooo…there are some capital letters in the title. See, I’m not against making a strong impression.
Starting your own starts. Good idea, go for it, you’ve nothing to lose! You could say the time it takes to prep the starts BUT really! That takes less than 15 minutes (after assembling all your materials). 
What do you need? Seeds, compost, container, water.
What to do?
I have a stack of egg cartons and I’ve used the plastic start containers before. I, Nedra, had trouble with the plastic containers. I found it difficult getting the starts out with the dirt intact. But maybe that’s just me. I’m a bit uncoordinated sometimes. I figure the egg cartons are made from recycled paper and will mulch nicely with the starts once they are put into the ground. 
Add compost. I used Gardner and Bloom Potting soil purchased from City Peoples. Make a hole to nestle in your seed. Cover with dirt. Place in a sunny warm spot for the seed to germinate. The seed package will tell you how long the germination process will take. Once the seeds sprout and a ready to transplant into the soil, Go for it!! remember to follow directions on the seed package. 
Just like people, plants are particular to what helps them to grow strong and healthy. (We just don’t come with instructions). So follow the given instructions!
The next time I will use a plastic, flexible cutting board for my working area. Easy clean up, just have to shake the board into the bag holding the compost. I also recommend lining the top of the egg carton with wax paper. This keeps the flat, rectangular top from absorbing the water from the egg-shaped partitions that are now holding the seeds.
I’ll see how this goes and report back in a bit. Super-duper…let me know if you have success.
