Post PCR-free; absolute abundance; yeast

I am new to NGS.
Goal is to find absolute abundance of yeast species in a mixed sample.
I plan to use PCR-free methods since PCR could cause amplification biased.

Plan is to use DNA fragmentase and size select ~300-400bp on Gel-> clean up->
end repair->A tail-> ligation/barcode/adaptor-> MiSeq 250 pair end.

From this millions of seq.(from different part of DNA) to figured out species and it's relative abundance??? Feels like i am missing some info. somewhere.
Any potential biased or problems?

above all this i do open for other complete new suggestions....
