Does a contract BA have to be an expert in a domain and look for contracts in that domain or is there a market for BA with good all round skills and many years experience?

I am employed as a BA in a permanent role. I have worked in permanent positions for most of my career, with a short spell contracting a few years ago. I would like to work as a contractor but I have worked in a number of domains rather than building up extensive experience in a single domain.  I am concerned that this would make it difficult for me to find a contract as clients would want a BA to be an expert in their domain.

 I would appreciate any views on this.

 I also have experience in Project Manager roles and although I would not want such a role again I am happy to take on some PM tasks it gives me a broader range of skills. Should I sell myself as more of a consultant than a BA?

Any advice will be appreciated.
