You found someone to do business with & perhaps that means you are doing a launch together or working on a product together, but you require to make definite that you are both doing an equal amount of work & benefiting the same as well. You require to make definite that you both have clearly defined tasks that your skills don't overlap & that you have least systematized as much of your product or your launch or your promotion technique as feasible, so you can be definite everything has been done. What does it mean to have non-overlapping skills? It means that in case you team up with someone to generate & launch a product together that there is only copywriter. There is e mail marketer. There is person making the videos, & so on. person could have plenty of tasks but you ought to clearly define who is doing what & only have person do it. That way in case you are the editing the sales letter the other person is not messing with it. If your partner is setting up the membership site & the plug ins, you don't mess along with his work & so on.
You might equally contribute in content, or you might equally contact your own e mail lists, but make definite that you have clearly defined whose job is whose so that you don't step on each other's toes.
Finally have a step by step technique that you can repeat, & confirm the results. That means in case you guys have agreed that a membership site ought to have a definite number of posts with a definite set of plug ins, with a definite personalized theme, you at least have that in some kind of a checklist so you can each check on what has been done, how plenty of emails have been written, how well the sales letter is converting, & so on so you can both feel as in case you have benefited equally & also contributed equally.
Not only ought to you define what tasks are each others, but also make definite that the person you are working with needs you as much as you require them. That might mean that the other person is a better copywriter, which is why they are working on the sales letter, or you are a better e mail marketer so you are writing the emails. Or the other person has access to more traffic or more associates & they are hooking those up. There is nothing worse than working on a project with someone, having to split the money & always be thinking in the back of your mind I could have completed this job, I could have completed that job. Make definite you can do something that they can not do & they can do something that you cannot do.
