Links here to let you know how to do it at home. Literally super basic tools required plus some Aqua Tape and the Seals.
Seals shouldn't be more than $10 each. Neck seal a little more.
In the future, keep plenty of talc on the seals - keeps them from doing this and makes getting in easier.
If you want someone to do the job for you, look for a Scuba diving centre...pretty much all diving is done in dry suits now and theirs are way way better than what you'll find in the wakeboard world. They are used to replacing seals regularly (they last 18 months at most under regular use).
You need to tell them that you have a "Membrane Surface suit with Latex seals." Get them to fit the nicest latex cuffs they have... cost wise it will be literally a couple bucks more and you'll be grateful for it in the future. Make sure they glue AND tape the joints.
Ask them to leak test it whilst it's in.... will probably be free and it'll be cheaper for them to fix it whilst they're working on the cuffs than to come back later... the smallest pin prick in the material can lead to lots of water later.
Hope that helps
