Balloon Quote for E-Party on July 25th

It will be around 11 tables as well as decorating the DJ and stuff like that... I was thinking of a few things:
1-Large Engagement Ring Balloon with maybe four latex balloons...
2-Latex balloons with engagment mylar on top
3-Silver Heart balloons...
4-Floating balloons...

Like I said, these were things I was just thinking about... I'm hoping you guys (the balloon experts) will have some more ideas!Thanks!!!

Oh, also, our invites were silver and white,... or favor ribbons are silver and white... we dont really have any color scheme... I think the inside of the place is mauve or something..
