You can find (local) designers not only through the "Find a Pro" search here on Houzz, but also through referrals from friends, family and colleagues. Sometimes "word of mouth" referrals are the best kind....especially if you know the person giving you the referral has similar likes/dislikes as you, similar criteria, etc....and they really liked their designer.

In my experience, I've also discovered that there are many talented and experienced designers that don't advertise here on Houzz, nor have a Houzz profile or a very active profile at all. So definitely research other sources....ie, ask local homebuilders (that showcase furnished models with a design aesthetic you like), local interior design showrooms (that carry furniture with a similar design style that you like), etc.

We actually found our top picks for a designer through a popular local publication/magazine here in the Dallas area, called "D Magazine". This magazine publishes several "Best Of" categories on an annual basis, from best restaurants to best doctors to best interior designers (for several years running now). And since moving here 20 years ago, we've found it to be a very credible resource. So, if there are similar types of local publications in your area, that could also be an "un-tapped" resource for you.

And I agree, seeing these designers portfolios online is important. But many of your questions can only be answered through phone call inquiries and interviews. So once you feel you have a solid list of several designers, make up a "pre-interview" list of questions you'd like to find out first....that can help narrow the field down to the 3 or so to interview in person.

I think you'll find that some designers may be crossed off your list just based on some of your initial criteria that they won't meet, i.e. some require a minimum project budget that's higher than what you foresee (ever) spending, time restraints/availability or some may require a larger-in-scope project than what you'd like to work on now. And quite frankly, some you may just not like or click with over the phone.

Btw, it's very important when speaking with these designers to discuss your budget....what you're willing to spend now for this project and perhaps over time (if you and the designer are ok with doing your project in "phases").

I would even suggest asking them about a specific living room (similar to the size of your living room) in one of their projects you like. Find out the approximate overall budget it would to complete a project like that....including all accessories, art, window treatments, etc. If that budget doesn't mesh with yours right now, see if they think it's possible to create a similar space in your budget (or anywhere close)....and if so, what compromises might that entail? (And are they compromises you're willing to live with?) Or.....if they would be willing to work with you in phases to complete that project over time and as budget allows.
