www.appraisersforum.com This is an appraiser forum similar to this one. They have a "jobs wanted" section were you can leave a post looking for a spponsor. There are also other posts doing with "newbies/trainees".
Each state has its own requirement for an appraiser. In Texas you have to find a certified appraiser who will sponsor you. Once that is done, you go throuhg training and during this process you will take your required courses. With all that said, it is very difficult sometimes to find an appraiser to sponsor someone. Most appraisers are very busy and don't have the time required to properly train someone. In most cases, they would prefer to hire someone who has a license or a trainee that has alot of experience. But to get the experience, you need a sponsor. Kinda like a catch-22. Good luck in you search.
