Generally, I advise against partnerships, because in most cases, you are better off with an employee or a joint venture agreement.
Maybe your best option is not a partner, but another type of business or business model that you can work on your own without having to give up 50% of any equity and control, which is what a partnership will do for you (neither of which are great options, in my book).
Joint ventures are good because roles are clearly defined and each party can walk away with respective businesses in tact. The same with an employee. If your weakness is sales, you could simply hire a sales person to work as an employee or on a contract basis. That way, if things work out, you can benefit from finding the right person to lead your team, and if they don’t, you can part ways without (again) giving up equity or control in your own company.
All of this is a long way to say look for other options before going the partnership route. I’ve rarely seen one that works … and the partnerships that do work are very rare.
