Subsidies, storage cost, import/export imbalances, separate uses and different demand drivers between similar commodities create arb opportunities. Once identified they can easily be executed without me and I could be circumvented. There is a fine line between sharing enough without giving away too much.
I know you need start up funding and your best bet is to borrow capital or to partner with someone. While there are advantages is getting yourself out there real fast, there are still some pros and cons. I would suggest the following:
a) Sit down and do a business plan or a projection for the next 5 years
b) Look at the capital that you would need to get you off the ground and to get you al least through the teething stages (say the first year)
c) When you have done that, look around you to see what do you have to put into the business, Eg: will you sell your car, how about the nest egg you had saved? what pieces of furniture can you sell?
d) When that is completed, check to see how near are you to the capital you need.
At that point if you still need a partner, carefully think why and who would you partner with. Remember the greater amount the partner puts it, the more they are going to require from you and the business. Think on what amount of shares are you willing to give up to someone. Who will do the marketing etc?
Remember your dream is yours, your partner must be able to see it through the same lenses.
There is so much to know, but carefully weigh all your options
