Adding a member to existing LLC in Georgia. Seek legal?

[Harry Williams]

I am wishing to add a member to my existing single-member LLC in Georgia. Me and a local partner are teaming up to purchase, renovate, and sell homes (revolutionary!). We plan to split any profits or losses 50/50 — keep it black and white. This requires an Amendment to my current LLC. My question is: should I seek legal assistance or will drafting our own simple Articles of Organization/Operating Agreement suffice?

Thanks for any suggestions.
