Ok state your collateral publicly and let everyone tell you if it is valid or not. If its valid, stable, 120% of what youre asking and can be easily liquidated if you default, someone will be interested. Stating you will talk about collateral in private usually means its not worth wild or you really dont have valid collateral.
Doing that to weed out time wasters and for personal reasons. This post means business, and any serious investor will be willing to negotiate privately ..Am not begging for money , am looking for an investor.
And many people here mean business. If you cannot post it publicly, then you may not be serious as you claim to be.
Best of luck.
