There is a reason why successful startups seldom order contract work especially early on.
Design is kinda different, yet most startups tend to have some competency and capability in that field(some frontend engineer more on the artsy/design side). If you did, you could have easily said that you are happy with the results and can take it from here, ask for source files. Since you pay by the hour and their game became to drag this it would be great to introduce a threat like that (even as a bluff).
Suddenly someone will realized that due to constraints(finding new agency would be costly) he became critical element of your business flow and will exploit that.
