Honestly, you run the very high risk of getting a plant that has hops that are no good for brewing. If you are absolutely dedicated to the idea that you must start with seeds, then you will have to wait a couple years until all your females flower, and selectively pick and dry (while keeping track of which is which) to choose the plants that produce favorable hops. A seed from a great plant can grow a crappy hop plant. It's why breeding programs are so involved and costly. And it's also why we use rhizomes, being genetically identical we have an idea of what to expect.
Good Luck and I hope you get to grow delicious hops there!!
