Hi! I would be more than happy to be a long term artist for your project. I'm not going to be going anywhere (fast), so even if you would like to commission me a few months later, I will still be available!
I am fully capable of copying the coloring style of your previous artist and my original shading was kind of similar anyways. I also like experimenting with a lot of different ways of coloring regardless, so that sounds fun! My lineart will be slightly different though because anatomy.
I do draw hentai, although I may not be able to cover all ranges of hentai (needs more practice). I'll be more than willing to see what you need and will let you know if I am not capable of doing a particular CG.
A quick example of things that I am working on:

Prices are of course negotiable. I am a little new to working with the visual novel market, but I do love playing visual novels myself (this was part of the inspiration for working in the VN market itself). I am estimating about ~$50 base for a sprite but feel free to talk to me about prices. I don't bite, I promise! I am open to adjusting the price as long as there's a clear instruction on the kind of work you need and the amount of time it will take. For example, outfits and expressions take extra time and will cost extra.
Here's a link to my commissions thread for lots of extra details:
Tada!
EDIT: Oh right, I forgot to mention, I'm currently having a bonus in which the first few people get free chibis with an order. So if that interests you (Since I noticed you're also looking for chibis), that might help a bit with your budgeting.
