From Wenlin Dictionaries
Regarding the sense glossed as "in a certain amount", here is what some other sources say:
PLC: so much; so many : 枉费如许工力 | have wasted so much labour
MOE: 若干、有些。如:「如许钱」。
GF: 这么些; 这么多 | 破费如许钱财。
鲁迅《故乡》: 海边有如许五色的贝壳;
Grand Ricci: Tant de; telle quantité de.
I think "in a certain amount" does not express the meaning very well, and that "so much; so many" would be much better.
