I've seen both Shy Tiffany and Sweet Monique so I understand the cutesy type you are after. Both of those WG's were excellent for me and definetely my type! I think they both had quite unique personalities so finding someone similar is difficult but I can recommend...
1. Jennifer GFE - https://www.adultwork.com/3431583
She is Polish, mid 20's, very cute and playful.
2. Or possibly Naughty Natt - https://www.adultwork.com/3419679
She is also Polish, mid 20's, cute and does a good GFE.
3. Or even Lovely Emily - https://www.adultwork.com/2795737
Polish, early 20's, very cute but has mixed reviews on UKP and can be a little cold if you catch her on the wrong day.
PS: I had similar frustrations when overseas accessing AW / UKP but I found using a proxy browser works really well such as Tor Browser - so you can click links from UKP to take you to AW without switching proxy on/off.
