JC,
There is NO circumstance where ANYONE can justify charging $1,000 to fill out this paperwork!! I would be suspect of anyone who would attempt to explain the rationale for this fee. There are plenty of sources via a VA service officer, DAV, VFW etc that can assist for free. There are also 3rd parties that do charge a fee which usually ranges in the $600 ballpark. Whoever this "firm" is, they are taking gross advantage of folks. The VA prohibits anyone charging for doing this paperwork. Generally you will find that this is done for free in consideration of "other" services such as financial planners.
They are correct in telling you that the VA has no "look back" as some other agencies do. The VA looks only at the assets from the date of application.
Don't overlook backing out all allowed expenses to bring that income level down. If you have not done so, visit

We wish you the best, and hope you find the right avenue to meet your dad's needs.
