Both the Wiki link I posted, and Ksand24's post above give you information on how to complete the process of bringing your spouse to the US. I"m not sure what you're having trouble with? Admittedly there is quite a lot of reading to do, ensuring you complete the correct forms and provide the requested documents, but plenty of people manage the process themselves.
If you don't feel up to doing this yourselves perhaps you should consider engaging a lawyer? However you will be asked to complete the forms yourself, and muster the required documents.
