Filing two forms of separate self employment income one with a 1099 and one without

How would I report tax on two forms of self employment income both from different employers. One of the incomes was under the $600 mark to receive a 1099-misc from my employer, and the second one was over the $600 mark and I did receive a 1099-misc.

 

Do I report the income under $600 as other income on the 1040 or do I have to fill out a two separate schedule-cs since the jobs are completely opposite?

 

If I have to fill out two separate schedule c's, how do I do this without the employers information such as their EIN and Address without receiving a 1099-misc?

 

If not, where do I report the income without the employers information?

 

On the schedule c do I put my net profit from both of these jobs or do I only do it for the job I received a 1099-misc from?
