This hand could be bid as follows:

P, P, 1♠, 2♥

4♠, P, P, P

The W hand has an LTC of 7 when partner opens a suit we can agree, therefore bid to game.

The 2♥ shows at least 5♥ and 8+ points as an overcall, a brave N may bid 5♥ after 4♠ given the fit says 3♥ and 2 off doubled is 300 - this is better than 420+ for 4♠.  The danger is we may go 1 more off or push them into a slam - no right or wrong answer here.
