Yes, it's a terrific stepping stone to providing premium services as well. You may find you and your team naturally gravitating to a core competency that really interests you. Such as voice services, media streaming, etc.

Just be aware of the potential liabilities. Clearly demarcate ownership of all assets in contracts. As well as any obligations for future services. At some point a client may decide they can save costs by "cutting out the middle man" and negotiating directly with you!
