There are so many decorators who are doing online work--Google some and find someone whose portfolio you like and who is budget friendly. If you have a list perhaps someone here can give you their opinion.

If you post pics that can be blown up then folks here can help.

Let us know what you need.

Here's a link to an article that describes 6 online decorating services:

If you're "terrible at decorating," as you said, then trying to do a room or a house by crowd-sourcing here on Houzz is going to frustrate you. You'll get so many conflicting opinions by people with no vested interest in your project that you'll really want to pull out your hair. Believe me I've been on these boards for years, and it's best for making one or two decisions, but not efficient for doing a whole room.

You can use Houzz to contact a designer who does online decorating, or maybe contact one of the pros/nonpros who regularly post here and work with him/her privately.
