If you're new to magick, working with one particular spirit may be the best route - Spirits of the Sun are great for success in almost any venture, but Jupiter is good as well, specifically for acquiring money.
However, if you were to evoke the spirits on their respective days and hours, over the course of a week, they can work miraculously in tandem with one another.
For instance, on sunday evoke a spirit of the sun, for success in the overall venture, at 1am, 8am, 3pm, or 10pm.
there's a good reference to the planetary days and hours here:
http://www.renaissanceastrology.com/planet...ursarticle.htmlThen you might follow with a spirit of mercury to augment your communcation, help these people see your point of view, etc. A spirit of venus to make them amiable to your goals (not just for love and lust, venus good for all relationships with people); a spirit of jupiter for the money aspects of your situation; a spirit of mars if you wanted to hard-nose them into it, although that's a bit volatile so early on, I'd say call on mars if you thought someone was trying to stand in the way of positive development, like for instance the oil tycoons.
They can all work together to do their parts, ruled over by the sun, which is why I suggest starting with the sun. This not only calls on various relevant forces to accomplish a goal, but turns an entire week (which I suggest personally to be the week leading up to the full moon) into an extended ritual. You might even make daily sacrifices to the spirits unless you want to be all CM about it and take the spirits to task. I find they are far more helpful and less likely to do what you want in a way you don't want it when you sacrifice and offer thanks. I know I'm more likely to accomplish a favor for someone to the best of my ability when they are appreciative rather than lordly about it.
You would instruct each spirit in it's particular task - the Sun spirit to See this endeavor through and give you success in your quest; Mercury to Clear all lines of communication and be heard by the investors; venus to make the investors sympathetic to your cause and want to help you out; jupiter to make them generous in their investment; and if you need it, mars to combat any negative forces who seek to suppress your cause. You should be sure to instruct each spirit to work in tandem with the others, rather than independantly.
If you wanted to work with the fifty names, which Personally I think is almost a bit easier than working with planetary spirits, i would work with Ziku (who can show you opportunistic moments in the negotiations, think 'where to dig', as well as being generally good for money endeavors), Zulum (who is excellent for all business ventures, and protects from those with an evil eye on your cause), possibly Gilma (to establish a permanent agreement, or you could say to build this foundation so that it will not falter in so many years), and Namru is certainly good just generally for any kind of science/research, etc.
there are suggestions for working with the fifty names here on the forums in the necronomicon section, and they also can be evoked to work in tandem, although if you were to work the system in it's entirety, you might also empower your bandar with those names, and have it carry out the necessary tasks.
There are also a host of sympathetic magickal formulas you could use, but i'm not as versed in witchcraft as spirit work.
