Here is a design I've made, it includes the steps you asked. Didn't do the back page since I wasn't given any information for it. The design is neat, clean and simple. But I wanted to add some 'life' to it, a 'personality' so it looked more approachable rather then extremely corporate and professional. Afterall you're doing a partnership so it makes sense that the design isn't too straightforward and blunt. I hope you like it, kindly message me for any changes.
