Hello! Congrats and welcome! I do think it is doable, but it will definitely be a fast turnaround on everything! As for cost and location, that'll depend on where you/most of your guests live. If you're on the west coast, Mexico might be a good affordable option and within your $10k-$15k budget. If you're on the east, Jamaica, the Dominican Republic, the Bahamas, etc. would be more affordable. I would recommend settling the date and location ASAP so you can notify people and send invitations and give them as much time to save as possible. And in terms of who you invite, other brides/wedding planners have mentioned that you should expect about 30% of the invited guests to come. You know your friends and family best though and how many would actually go, so just user your judgment in deciding how many you can safely invite without breaking your budget. Good luck!
