Just reading the descriptions and clicking the links (where available) is enough to tell you that there isn't a single functional escort agency in your list. They're all independents, no longer operating, or both.

I don't think anyone on here will be able to recommend a lesbian agency, but if you want to keep looking read this first. It's for men wanting to escort women, but the same issues apply to you.

A while ago a lesbian escort who advertised on adultwork.co.uk/gayswap.co.uk contacting me because men tried to book her even though she advertised as gay, and she decided she'd be willing to do ffm threesomes. She told me she was making enough from female clients to supplement her student loan, but I suppose she wanted more because the last I saw she'd gone bi.

Lesbians aren't as easy as straight men so you're probably in a better position than the guys, but I haven't heard anything to suggest that you can make a living as a lesbian escort. If you want to try it as a side job and don't find an agency (or if you do and want to improve you chances), set up as an independent. This site already has just about all the information you need to do it, and if you have more questions you can ask. See if you can get a presence on local lesbian forums (even if they won't let you advertise, just being around and mentioning what you do so that people know you exist should help). I know a girl who booked someone who promoted herself in that way.

There are female clients out there, but there simply isn't enough of a market for an agency to be 'lesbian only'. So although there are loads of them that would have someone for any woman looking to book another woman, I know of no agencies that only do this aspect.

Similarly, the women I know who've advertised as escorts in places like Diva say that the vast majority of the (small) response they get are other women wondering about being a lesbian escort too.

You'd probably get more of a response if you did threesomes with mf couples. The imbalance between the demand from such couples and the supply of interested bi women is such that you can specify things like 'I'm not having intercourse with him' and still get work.

I know a few people who get more than that by 'trolling': getting people interested first, and only then saying 'oh, you'll pay my travel expenses etc, won't you?'

Ethically a bit dodgy, but there does seem to be at least a small market out there.
