I agree with Thomas, though: you won't need one until you've dug into the investment itself and done your "due diligence" with the people and company involved. There are scam investments all over the place that end up being Ponzi schemes or just outright frauds. Most of these people are going to be smooth talkers; they'll get you jazzed as hell about making tons of money. You won't even know you've been robbed until they're already gone and either out of the country or sheltered in bankruptcy. If you have that kind of money to invest, I'd guess you're probably in a country club or something like that. If you spend half an hour in the club's bar or sauna on the weekend, you'd find several people (especially doctors) who got scammed on deals like this.
First, presume that anything that sounds to good to be true probably is. Second, anything that offers rates of return higher than... probably 7 or 8 % will likely be a scam or at least very high risk. Third, limit your investment in these kinds of deals to whatever you'd be willing to take to Vegas and lose on a single bet at a roulette wheel. Fourth, understand there is no quick route to lasting wealth; anyone who says otherwise is trying to sell you something you don't need to be buying.
This isn't the answer you are looking for.
You don't need a lawyer UNTIL you have done enough due diligence about the person you plan on doing business with; have checked out their references; looked at their past performance; checked their credit report; and a few other things.
To put it in as few words as possible: even if you owned 100% of a company with zero assets, and zero money - you still don't have anything. Your legal document is only worth whatever the company has for assets at any given time, times your percentage of that company.
So, avoiding start-up companies, and companies in business less than 5 years, and focus on a small company that has been successful and profitable that wants to grow, and needs money to expand. Then you can get a lawyer to draw up the contract, but include a provision that allows you to approve each purchase using your funds, and allows you retain ownership of each item purchased. This way you can retain control of your investments and resell the equipment (legally), if you need to dissolve the partnership later for reasons yet unknown.
Do whatever you want - but you can walk into any crowded building and ask for partnership horror stories, and find alot of people who were too trusting, and lost their entire investment.
Maybe you already know this, but it doesn't seem likely from your wording of your question.
Good luck by the way.
More and more people now are into investing properties, and usually investing in a property is a long term business and earning money will really take some time. A property at Miami Beach real estate market is a good investment, because there are bunches of buyers and sellers in the market that can really help you a lot in earning a lot of money investing a property.
Look for a corporate lawyer. Don't invest more than you can afford to lose.
I would not invest in something unless I could control it. Given your situation, you will have no control.
Call the local bar association for attorney's names.
I have seen a few opportunities online in my area from people looking for $20,000-$30,000 with me receiving an ownership percentage of the company as a silent investor. I would like to find a lawyer to at least look over whatever it is that needs to be looked over to make sure everything is legitimate and i am not being scammed in some way, does anyone have any experience in doing such things or know which kind of lawyer i need to get in contact with? Thanks
