From the benefits of this short article1 is an important review of the rankings of walīs for marriage, as quoted below (read the article at the URL above for more benefit):
Legislated Ranks of Wilāyah in Marriages
Let us take a muʿmīnt to be clear on the legislated ranks of wilāyah in a marriage contract. The following are the order of ranks, each of them being sound-minded adult men of the same religion:
Grandfather (from the father’s side)
Great Grandfather (from the father’s side)
Oldest Full Brother
Next Oldest Full Brother (and so on…)
Oldest Half-Brother (from the Father’s side)
Next Oldest Half-Brother (from the Father’s side, and so on…) 
Oldest son of a Full Brother (Nephew)
Next Oldest Son of Full Brother (Nephew)
Oldest Son of a Half-Brother from the Father’s side (Nephew)
Next Oldest Son of a Half Brother from the Father’s side (Nephew)
Grandson of Full Brother (oldest first)
Grandson of Half-Brother from the Father’s side (oldest first)
Oldest Paternal Uncle
Next Oldest Paternal Uncle (and so on…)
Oldest Son of Paternal Uncle (Cousin) 
Next Oldest Son of Paternal Uncle (Cousin, and so on…)
Oldest Great (Paternal) Uncle
Next Oldest Great (Paternal) Uncle (and so on…) 
Important: Each of the above mentioned walīs has the right to appoint someone on his behalf to act on his behalf. So in this case, if the father appoints the brother to act as the walī, then he is the official and accepted walī, even in the presence of the grandfather, since the brother is the father’s chosen trustee and takes his place.
After these relatives have been exhausted, then a woman may seek to appoint a walī from outside her family through the Muslim authorities.

Reminds me of the time Shaykh 'Ubayd informed us that the wakeel should be appointed by the Masjid/Imām - that it should not be random. Even though the general requirements in the sharee'ah don't insist upon the Imām of a masjid being a wakeel (for those who don't have a walee from their relatives). The Shaykh explained that this is necessary or problems would occur. Interestingly and sadly, some of those who affirmed themselves as wakeels (DIY) made horrible errors not knowing the rights of the female, the mahr, making poor judgements etc. It's not an easy task. There is wisdom in what Shaykh 'Ubayd noted about the issue.
