Jeicobu
I think searching kanji for your name is one good way for studying kanji.
There are certain people who use Kanji for their name.
Half blooded people and naturalized people commonly use kanji for their name.
Nowadays many Japanese people make western-sounding names with kanji for their sons and daughters(!).

There is no kanji that is pronounced "jei", most people use mixture of "ji" and "ei" like Jay Kabira / 川平慈英(TV talent).

治 [ji/chi/osamu]administration, cure
恵 [kei/e/megumi]give/（God’ｓ）bless
護 [go/mamoru]defence/security
輔 [ho/fu/suke]help/assistance
*red letter words are Kun-yomi reading.

This kanji name sounds "ji-e-go-ho" for common Japanese but I think it is acceptable range for pronouncing as "jeikobu".

Nonetheless, I think it is unnatural to use four kanji or above for one personal name.
