Best Wishes & Congratulations, Sheila & Sam!
You didn’t mention what kind of help you need or how inexpensive the wedding needs to be.
So, I’ll suggest selecting a venue for the ceremony (home, backyard, beach, your place of worship) and a venue for the reception (home, backyard, beach, restaurant, country club). Decide on a menu (and cake).
Select an officiant (clergy or civil). Discuss wishes for ceremony and what roles children will play in the ceremony.
Select a professional photographer and videographer.
Clothing for bride & groom, color scheme, decor, flowers.
Don’t forget a Fla. marriage license (approx. $95) from any county courthouse in the state. Get it no more than 60 days before the wedding and no less that 4 days before the wedding.
Best of luck,
