Any advice about paying for an internship?

So I’m a third year biology student at SFU and I recently saw an opportunity for some experience in conservation with GVI. For a two week internship, it would be $4000 not including the flight and I’m beginning to get second thoughts after reading peoples experiences and thoughts with GVI.

Conservation jobs are competitive and I’d like to get ahead, however, if future jobs will ignore this because I paid for it, should I wait for a better opportunity?

Do you guys think this is worth it?

Any comments and advice would be helpful :)
