Hello @kimismurf , and welcome to BYC!
I would suggest maybe looking for a coop on craigslist - if you can find something affordable that you can use in the short-term, you will buy yourself plenty of time to work on building your own coop if that's what you would like to do.
I think that building your own is certainly achievable, even for a beginner, but the concern would be that your chicks are going to grow up very quickly - I'm in the process of building a coop now, and it is taking quite a bit longer to build than I planned, and I've had to scramble to find more space for the girls while I'm finishing the build.
As far as hiring somebody, if you know a reliable handyman/carpenter, go ahead, but I would still be concerned about how quickly they could finish the job - and of course this would be more expensive than building one yourself.
Either way, good luck, and enjoy the ride!
