take this with a grain of salt because in the end it all depends on what someone is willing to pay. but it seems like from what i've been seeing is female spiders that size are going for about $0.50 a gram. so she would be in the $300 range. and the pastel i havent seen a whole lot of them that size in my area. but i'd venture to say $250 wouldn't be unreasonable as hatchlings are going about $125. please speak up if im to far off the mark folks.
Unfortunately the market isn't what it used to be. IMO, realistically You can expect to see maybe 250 for the pastel because of her size. The spider I can't see you getting more than 175-200 for.

Edit: sorry my dislexia is messing with me. I thought the spider was 300 grams lol. I think you can feel confident in pricing them both at 200-250
