Worry not, Bianca. There are a lot of available party planners out there. Sharing with you a link for an fb page for events planner. Simply post what you need including the range of budget you consider and location and they will be the ones messaging you for proposal. :) https://www.facebook.com/groups/600687213305386/
You can be the party planner yourself! If you plan ahead of time, you can prepare everything all by yourself. I know lots of moms who did DIY for their LOs birthday and they pulled it off so perfectly! Check Pinterest too, if you want more ideas :)
