Design me 7-15 logos a month

I am looking for a designer or a design team to design me 7-15 logos a month for different clients.

For each logo I need:
- 3 concepts
- unlimited revisions
- source files (PNG, JPG, AI, PSD, PDF)

Please send me this information: (without it I will not consider you)
- your price
- how long (days) do you need for the first 3 concepts and then for revisions
- 10 of your best logos you made (or even better, a portfolio)


For every 4th logo I need a CID design (business card, letterhead, stamp).

Thanks!
