I checked the past sales for the last keyword "planners" at Namebio: the closest domain I can get on the lower range is "beliefweddingplanners.com", which sold at US$205; at the higher range, the closest comparable domain is "asianweddingplanners.com", which sold at US$236. Both domains have 6 syllables and are 3-worded, while your domain has 5 syllables and is 4-worded.
You can sell for less than $200.
