Hiring contractors.. the legal stuff

[Jackie F.]

I know at some point I am going to have to Hire an acquisitions person.. I would pay them on 1099 contract a percentage of the profit.. 

I know of course a contract agreement would need to be drawn up.. but how do I legally hire a 1099 contractor.. 
What forms do I need to fill, when do I send them to the IRS right away or just store them on file for tax time.. What exact steps are taken?

Also what is the steps for hiring contractors for flip projects and what not .. are they paid 1099 as well, Do I have to file any tax forms for them.. OR do they simply charge their price and I pay it...

Sorry, I overthink everything.
