I think people are confusing the most valuable or strong vs weak letters used in the context of LLLs, LLLLs, etc. While there are strong and weak letters in brandable domains, it doesn't completely translate. It has more to do with context and brandability. When selling letter domains, the value of the letters is more related to acronyms (do companies have names that start with these letters?) or foreign uses (like representing Chinese letters/words/etc). When it comes to a MUP (made-up pronounceable) brandable, it has more to do with the sound of the word, the memorability of it, ability to spell, uniqueness, etc. Obviously "q" can throw a wrench into the spelling, etc sometimes, but it can also boost uniqueness and memorability. I personally have some domains that replace a "c" with a "q" to make strong brandables that I am developing into brands.
As far as this domain goes, I think it has a lot of potential being a 5L pronounceable with a slick look to it. I think the "q" actually has something going for it here. That being said, it definitely doesn't leap into the premium category for me and "q" brings a rough sound to the name as well. The domain will need strong marketing to remember the spelling. Fortunately, I think think the shortness of the name outweighs that here. A lot of short brands (4-5 L) tend to fail the radio test far more than their longer counterparts. Part of that is because shorter domains tend to be easier to remember in the first place. Also, this doesn't have any difficult blocks of consonants - I love VCVCV domains.
I put it at low-high $xx reseller and mid $xxx - low $x,xxx enduser. Try submitting it to BB and see what they think. And remember, even if it is rejected doesn't mean you can't still sell it (I do it all the time).
Hope this helps!
