Hello,
My name is Chris. I have a very good experience working with databases. Your post is clear to me, however, you forgot an important detail: Which is the format of the existing 3 archives? Are all 3 files in the same format? My bid is typical, in order to clarify this point. Please reply, and I will provide my proposal, adjusting my bid accordingly if necessary.
Looking forward to hear from you,
Kind regards,
Chris (chriskerpini)
