Perhaps you could send your resume to furniture stores they can always use designers ,also Real Estate companies they are always in need of staging in homes for fast sales . Advertise locally by placing ads in your local paper ,volunteer to redecorate friends and relatives homes ,make business cars and drop them off in paint stores ,fabric stores,if you are allowed to pin some in a bulletin board this would also help. Stay informed on how much the Designers in you are charge is ,don't go over board with you fee, it takes time to built a reputation and clientele, so give yourself plenty . Good luck .

The advise that you get from houzz.com is from professionals like myself and also from people who aren't professional but who enjoy commenting. The site is not really set up for solving very complex designs such as a complete house. I enjoy taking a few moments out of my busy day helping out when I can, but there is no compensation involved and I can't spend much of my time here. Houzz can also be used to find a professional to hire in your part of the world. We have clients who have found us through houzz. I don't know if there is a pro near you, but hopefully you can find a local architect for you to help you design your house. Of course you can post any questions that you have and you never know what great answers you will get.

Leave them alone if you are not going to change them out completely, Halfass will look worse in my opinion.

I feel partitions are not needed. You already have too much for the space. Adding a partition will shrink the space further. The simplistic solution, you do not wish to discard any furniture would be to paint all the walls in lighter pastles. And use some wall painting frames to highlight certain walls.
