If the university has made a mistake on your transcript then that will need resolving because those hours are not sufficient. My uni made a similar mistake but I went in person & got it corrected. As an aside my maternity & paed hours were almost identical to your proper ones & that was plenty!
As for the rest SD is right - as usual!

Only you can decide what's best for you & yours. You may even consider another country instead - there are other options - but you need to decide for yourself. If you want it - it's worth it.
Also heed what SD said about not using an agency - it's easier than you think!
