P.S. I do wonder if it isn't hurtful to announce that you are only attracted to white girls, or skinny ones, don't like bald guys, short ones, etc. I know women who do really think physical appearance is very important too. It's not always men. Is it okay if women specify physical requirements too? Preferences can really wound people. Is there a point where preferences become wrong? Are some attributes okay and others off limits?
To be honest, I think if an attribute matters to you... it's better to mention it. Let's consider reality, if someone has an attribute you want to avoid, or doesn't have an attribute you seek... would you marry that person? Chance are, no you wouldn't. So why go through the whole song and dance of getting to know each other when it's ultimately futile?
Personally, I see absolutely nothing wrong with sisters mentioning what they like and what they don't. It's realistic. If anyone has a problem with that, then they need their head slapped for thinking the sister has no right to refuse their proposal if not for that attribute... she has every right to do so, for whatever reason she wants. Yes, the Prophet (saw) said to marry women off to whomever asks so long as he possesses taqwa and deen, but it's implied that she be married off with her agreement (i.e. the wali shouldn't refuse the marriage proposal for a silly irrelevant reason if the couple want to get married, otherwise that will cause a fitnah).
And I don't think anything is off-limit either. Like I said, if it matters... it matters. We could discuss all day long as to whether an attribute should or shouldn't matter, but at the end of the day it's subjective, and regardless of what I or anyone else thinks, you'll still choose a spouse based on your own criteria. Ultimately, it doesn't matter what anyone thinks but yourself.
What I would say though, is to make a list of preferences and dislikes, rather than a hard list of must-haves and must-not-haves. It may be that someone approaches and they have something you dislike, or miss something you're looking for... but their other attributes will make up for that. They may also possess something that you weren't looking for, but you need (a lot of sisters need patient husbands, yet hardly ever list this as a criteria). And I know a lot of brothers that don't like darker girls, but if Beyonce came knocking on their door, they'd jump to attention!
The best of shayateen is the one who breaks up a marriage... so what of the one who prevents a marriage from taking place? And the reason those shayateen are praised by Iblis so much is that, by breaking up marriages, you can break down the family structure, and in turn society, and this is where the major fitnah get introduced.
So, be easy, and facilitate the marriage... but that doesn't mean marry someone you're not attracted to.
Oh, and forget about the wealth a person has. This is from Allah (swt), and he can give wealth and take it away at any time. I don't understand why people cling to it so much. If the brother is hard-working, Allah (swt) will provide him with enough rizq to support you, and it would be a blessing to not have any excess that you have to account for on the Last Day, unless you're confident you can spend it in the cause of Allah (swt) and make it count for you rather than against you
And Allah (swt) knows best
