Alterations by Gina?

Has anyone used her?
Is she reasonably priced and dependable.
I got a very plain David's Bridal Dress and I still want it to be simple but I want to add some beading and my friend said she researched Alterations by Gina.

ETA: If anyone knows of another place that will add things to a dress please let me know!

Iman in Oyster Bay designs dresses, so she might be willing to customize yours. I put 'custom wedding gowns, Long Island' in Google and got a whole bunch of listings, but she had a description . . . .
