I worked last night for the first time (which is why I didn’t ask the girl herself) with someone named Qin. Pronounced “Chin”. Who decided that the sound ‘ch’ would be rendered in English with the letter ‘Q’. And why?
Wouldn’t it have been more logical to spell the name “Chin”, since the name has to be rendered in a completely different way in English?

One thing you don’t seem to have picked up on is that all the romanization systems currently in use are systematic - that is, a given sound is always spelled with a given Roman letter. Which wasn’t always the case. Clearly she used Pinyin romanization; there are other romanization schemes that indicate that sound differently. In the older (also systematic but rather confusing) Wade-Giles system, for instance, it would have been Ch’in.
Wade-Giles and Pinyin differ in their approaches; Wade-Giles depends on the reader having some knowledge of Mandarin syllable structure, which allows them to recognize that, say, these four syllables all begin with different sounds: ch’ing, ching, ch’ung, chung. In Pinyin, those would be qing, jing, cheng, and zheng respectively. Each initial sound in Pinyin is spelled differently, and even if non-speakers won’t be able to pronounce them all correctly, my suspicion is that for beginning students of Mandarin, Pinyin is easier that way. Further, it prevents the confusion caused by frequent omissions of those all-important apostrophes.
So the simple answer is that Mandarin has a number of sounds very much like the English “ch”. As has been touched upon, “Qin” is not actually pronounced with a “ch” sound precisely, although it’s liable to sound that way to someone who doesn’t speak the language. (As a matter of fact, Mandarin doesn’t have anything corresponding exactly to the English “ch” sound.) The reason for the odd choice of Q to represent the sound is that CH had already been taken; because the sounds of Mandarin and English don’t line up that nicely, some letters had to be press-ganged into service representing totally different sounds. Thus Q, X, and ZH are used to represent sounds that a naive English-speaker would likely hear as “ch”, “sh”, and “j”.
Further, there are some regularities in the way consonants are spelled out in Pinyin. There are three parallel series of fricatives and affricates in Mandarin, spelled in Pinyin as S, C, Z; X, Q, J; and SH, CH, ZH respectively. The oddly-spelled X, Q, J series is in complementary distribution with the other two series - that is, those letters can’t appear in the same phonetic environments (thus you can have “qin” but not “chin”, “zhao” but not “jao”). These three, the palatals, are thus spelled differently in order to point out their distinctiveness from the other two series. Whereas in the SH, CH, ZH series, the H is used to mark that they’re retroflex (R-like, pronounced with the tip of the tongue curled back against the roof of the mouth) equivalents of S, C, and Z, and appear in the same phonetic environments.
So there is some underlying logic to Pinyin. It serves several purposes - unambiguously indicating the Mandarin pronunciation of a word; providing a single, unambiguous representation of Chinese names and place names; helping non-native students of the language; and even serving as a mechanism to order card catalogs and dictionaries (particularly so outside China; complicated but usable methods involving the structure of the written Chinese characters exist that are still used for many such purposes within China.) All of these things represented separate demands on the development of the romanization scheme; Pinyin has the additional advantage of providing a rather elegant illustration of certain features of Mandarin phonology, as with the aforementioned use of H to mark retroflex sounds. So even if a name is not immediately pronounceable to Westerners, that’s not the only goal of the Pinyin system.
