Why not the ATP?

=start_date+SIGN(B1)*SMALL(IF((WEEKDAY(start_date+ SIGN(days)*(ROW(INDIRECT("
1:"&ABS(days)*10))))={1,2,3,4,5})*
ISNA(MATCH(start_date+SIGN(days)*(ROW(INDIRECT("1: "&ABS(days)*10))),holidays
,0)),ROW(INDIRECT("1:"&ABS(days)*10))),ABS(days))

it is an array formula, so commit with Ctrl-Shift-Enter.
