As dumc already said , you should check quality before uploading so large volume of images.
Many ppl do this activity from many years and they have not yet reached the 100.000 milestone.
It needs patience and time.
I suggest you to be very selective and choose only the ones with sale potential and then check them all at the 100% of resolution searching for high iso noise or a not very good sharpness.
Correct them all and check your keywords really carefully cause is not secondary in my opinion.
I am slow and in 2 years (with at least 1 hour a day ) I have circa 1000+ items for sale on 10 agencies... but with a good sale rate . Good luck anyway
